I'm not having it. Next you'll be telling me the earth is spherical...
😝🤣🤣
Yo Dave happy new year mate 🎉
Are you saying it's not Dave?! Maybe I'm wrong?! lol
Hehe it's called inertia when the car accelerates forward faster than you can & when breaking slows quicker than you can.
Flat earthers are my favourite people to talk to. Real life NPC's 😂
It would be much quicker to say "the car accelerates before the person does and decelerates before the person does."
If only everyone understood as easily as you do mate, yes!
I really didn't realise this was a topic of discussion.
Apparently it is mate! lol
I felt the same way when I found out that some flat earthers aren't actually trolling. So much knowledge at our finger tips with the internet and yet the most basic things slip people's understanding.
@@theshawnmccown They’re my favourite people to troll! I can’t help but comment on every flat earther video I come across 😂
Another fun one…. If you hover a drone in a stationary train cabin, and then the train starts moving, what happens to the drone? 🧐
Nothing, the train moves the drone stays where it is... unless you tell it to do otherwise... Just like we would if we were floating in our cars and not sat in a seat.
Haha yep. Amazing how many people get this wrong.
Well it's very simple:
Acceleration of car: surge forward + pitch up (push against the seat and for sustainable g-force feeling using gravity)
Deceleration of car: surge backward + pitch down (to push against the belts + sustained G-Force acceleration using gravity)
Hi Thanos, how's it going?
I don't agree with surge backwards but it is "closer" to real life than going forwards when braking! lol
I have a setup similar to 'Race Beyond Matters' were just the seat/pedals move via three fast/powerful servos. Feels excellent. @@KarlGosling
@@KarlGosling Thanos is strictly speaking correct - braking/accelerating are two sides of the same coin - it’s just a rate of change. If you accelerate you are subject to positive g in the longitudinal axis, if you decelerate you are subject to negative g in the longitudinal axis. Motion is relative. You are also spinning at enormous speed while hurtling round the sun as the entire galaxy hurtles through the universe but you don’t observe this speed because your frame of reference isn’t moving and the accelerations are imperceptible. The speed of motion doesn’t matter since it’s all relative anyway - it’s the rate of change (aka acceleration) that you feel. The error is in thinking the sim behaves in the same way as the car, you can only try to replicate forces as best you can. If you want to feel the vehicle deceleration, it is the exact reverse of how you feel the vehicle acceleration… I disagree with your assessment that negative surge is not accurate for braking.
However, it has to be said - just do what feels good to you. For example for flight I use a setup that isn’t strictly accurate, but gives me the best sensation in flight… who cares as long as you’re having fun.
Thanos and Zeeflyboy have it right! Flag Ghost here 😉 We can’t really simulate a car’s gforces so we don’t always mirror the car’s movements. We instead try to mirror the “feel” of the car’s movements from the driver’s perspective. We are tricking the brain by manipulating the senses.
I am in my 40's and maybe things had change in school, but I was tought basic physics in primary school. Then in high school, this basics physics were explained deeper with more interesting formulas... But anyway, I don't understand that this need to be explained. Karl next time that someone discuss this instead of make a video, send them to a library to check the books they should had already check a long time before in their lives.
lol I only wish it didn't need explaining mate!
Physics is fun. Inertia is a good one.
People think the sensation of being pulled into your seat is moving backwards... never heard that one, lol.
It's crazy isn't it but I read it all the time in the comments with motion related videos.
Great video Karl, lol I was laughing the whole time! It's amazing that this needs to be explained. haha
Glad you enjoyed it! lol
I'm stunned that this needed to be explained. Good content.
My 2012 SRT8 Superbee has so much torque from it's 6.4L Hemi that it doesn't actually pull me down the road. It rotates the earth underneath me. 😝
Remember having this argument with the internet simulation 'experts ' over 10 years ago when I started building DIY motion simulators using knowledge gained working on Defence hardware. 🙂
This all makes sense for flatscreen for sure. I agree that surging forward is the way for accelerating since you’ll feel the pressure on your back, however, in VR, motion compensation will be needed since it’ll look the opposite effect moving forward on acceleration. Braking, I also agree that moving backwards for braking isn’t the way since there’s no pressure to be produced on the body in the sim, best to use a seatbelt tensioner or just pitch down when braking.
Spot on Karl, the driver is stationary and the car is pushing forward into the driver's back on acceleration, you're never being forced backwards as some seem to think, the car is forcing itself forward against the driver, the driver is "floating" within the car and not fixed and solid/rigid. A lot of sim folk don't really understand the dynamic of motion platforms with these levels of immersion as most can''t afford it or don't want to spend high levels of money on such equipment... a seat mover doesn't count because that concept of motion isn't correct, a seat never moves independently to the rest of the rig, it flexes but never moves. Well presented mate as it's not a subject that's easy to present due to the complexity of motion, even if it is only simulated whilst stationary/static.
I'm actually running a Mk1 Prosimu T1000 3dof platform with the old SCN6 actuators with 100mm travel up front and 80mm travel on the sway/sideways motion mate, I've spent a long time tweaking and tuning to suit but as it's only 3dof means some sensations aren't quite as there as a full on platform but I'm managed to hit that sweetspot with it now. When watching rigs move, they'll move in what appears to be an incorrect movement however, the sensation it gives to the driver is relateable to the real movement, it's odd to look at when looking from an observer perspective and see these odd looking moves, to the driver it feels similar to the sensation to what you'd feel in real life so to speak...
I agree. I find it interesting that it's not intuitive for most people.
It's Newton's first law of motion - "An object at rest remains at rest, and an object in motion remains in motion at constant speed, unless it is acted upon by an external force".
We are an object in the car. Our body will stay at rest until an external force acts upon it. That external force is the car moving forward. Upon that action, that's when we will start "moving" as well.
Also spot on @jaytoppo1670 and thank you for your words on my presentation, I think it came out ok considering it was off the cuff!
Yes exactly!
there's actually 2 ways to do movement, you can replicate the car movement or you can replicate the g forces, and as both are exact opposites of each other it's a choice in which one software wants to use, so both ways of doing can be correct depending on what you are using the movement for
No worries!
Its all about inertia! When the Car push you to forward, the inertia pull you backwards!! When you brake, the Motion has to move Back, so your Body goes forward, When accelerate, Motion has to move forward to push your body backwards.. 😉
an object's mass remains constant, while its inertia changes with speed, ultimately preventing travel at or beyond the speed of light, so its your inertial mass that changes as the car moves or breaks and this is what you feel and is simulated in a sim rig
It's when you start using the tilting of a sim rig to simulate acceleration and deceleration that it dose the opposite of what it should.
on a rig you aren't in a moving vehicle so the sensations you get are basically variations of pressure from the seat against your back as it tilts in various directions.
In a real car when you accelerate the car moves and you get the feeling of being pushed into your seat, the feeling of pressure between your body and the seat increases.
In a simulator which tilts when you accelerate, the front of the rig raises and the rear lowers to use gravity to simulate the pressure your body feels during acceleration. The problem is during the initial transient movement of the rig while starts its tilt. The leaning back tilt of the rig to point you slightly upwards moves the seat away from your body giving a less pressure feeling between your body and the seat, which is the opposite to what you feel in real life.
That’s where the longitudinal surge axis helps - you combine the initial push/pull from the surge for the impulse and transition into a tilt for the sustained force while washing off the longitudinal.
Using pitch (tilt) is not good at all for simulating acceleration or braking, it can be used in conjunction with surge (as you do actually move forwards then) but otherwise just like with a seat mover it feels wrong... I used to run a seat mover but soon grew to dislike it and went back to no motion.
@@KarlGosling Yeah, I keep telling myself that as a good excuse on why I'm not about to shell out 10k spondoolics for one.
Another very informative video!
Thanks mate!
I don't have the problem where my surge platform should move (forward or backwards) as sadly I don't own the surge platform. However, I think I might understand where these comments come from. I can imagine 2 approaches to use the surge platform - First one, to imitate the move of the car accelerating. Second - to focus more on the g-forces imitation and compromise the real world. Now, this is sim racing so we have completely different actuator travel to what the car is doing - so that's the first challenge but also we have the personal feeling. We can see it for instance when it comes to FFB settings. There are so many of them and everyone tries to tweak it, so it feels more "real" for them. Additionally, in sim racing we have tools like wind simulator where even you made the video why this is a great tool (I have one, used your discount code and absolutely love it). Does the wind simulator exist in the real life? not really, not needed there. But things like wind curving is amazingly tricking our brain making us feel like the car is rotating while in the sim rig. I think with the constant battle for the immersion in the sim racing world there are tricks which do not make sense from the real life perspective but helps us to be more immersed. I am with you that if I had the surge platform, I probably would start from the settings you describe. However, my curiosity would make me try the backwards option as well to see how it feels. If it would make me feel better, more immersed, my body would feel that sort of move as closer to what I would expect in the real world - I would stick to that one which tricks my body better and I would have no problem with the fact it is working completely opposite.
Is it just me or does this feel like an audtion for "Physics for kids" ? :D
Could well be mate! lol
It's just a matter of the position from where movement is determined during acceleration of the vehicle.
If the observer is standing outside of the vehicle, both objects (occupant & vehicle) are moving in the same direction during acceleration, in relation to the observer.
If the observer is inside the vehicle (as in: a camera mounted to the vehicle), the vehicle remains stationary (with the observer), and the driver/passenger moves backwards (in relation to the vehicle), until such time as both ground speeds match, at which point both vehicle and occupant become stationary again (when compared to each other).
The problem we have with sim rigs, is that there is no forward movement, as the whole rig is sitting on the floor.
I think this should be the actual topic of the conversation. The thing with sim rigs is that there is no way to simulate the force of the seat pushing you forward that makes people feel like there's a force "pushing them back onto the seat", which is the consequence of the difference in accelerations between the seat and the person. I also don't think the phrase "being pushed back into the seat" is 'wrong', it's a matter of the frame of reference as you said.
@@Madkangaroo Exactly this. Neither 'side' is wrong, per se; they are just not talking from the same perspective or 'starting point'. Once everyone agrees on the basics/fundamentals of discussing this topic, everyone will be in agreement about the perceived and actual forces a sim-racer experiences.
I love Karl's videos, but he gets a bit, ....err....stubborn when it comes to things like this; and yet he is not even saying anything different, but in a different way or from a different aspect of the conversation.
All this is very weird in the sense that seat movers do move back... once you accelerate the seat inclines backwards, and it does seem to work and give a sense of acceleration. But perhaps what gives this sense is gravity that in that moment starts to act at your back since it's now inclined. Anyhow, no wonder this is a big topic of discussion (and argument)
A seat mover will do exactly what you tell it to (forward to backwards under acceleration)... but seat movers are very poor solutions (having had one) I do not recommend them as they cannot simulate anything with any degree of realism... can add "fun" to racing titles though.
Well I never ever days a school day, cheers fella.
if theres ever an Explanation to take back to those stoner days i had 20 years ago, this would be it...... and A... ahha moment and batman mobile for explantion too, Pure brillance 👊 Made my day !!
lol Thanks mate, it was quite comical to produce!
Hi Karl, do you have any information on the Inizio 2 from Formula Sim Rigs, thanks in advance
I do not mate sorry!
Ok ......Try this...😃😃
.i use the sfx100 with surge platform and my steering wheelbase is mounted on the outer and steady (4 actuators)frame. The seat and pedals are mounted on a moving surge frame with also mounted seatbelts on the outer! frame
So when i brake ....the seat slides forward just a few cm (and then the seatbelt logically gets tighter )
It really gives a braking sensation like being pushed out of your seat (also cause your upperbody comes 3/4/5 cm closer to the steering wheel)
Acceleration is even more minimal... and better simulated with a little pitch when shifting gears
Surge should ONLY simulate the braking in my opinion.
i dont see so many rigs with this solution..... but i SURE recommend it
Remember it is all about feeling
AND when somebody uses surge under acceleration forward......MAN...its just stupid cause your platform moves max 2 seconds
but the accelleration time on track to the next corner are WAY longer then that
forgive me for my english lol
so i had an accident years ago and i hit a stationary car and my seat belt left bruises on my chest , so that was the car stopping and my body being pushed into the seat belt right ?
Your momentum from whatever speed you were travelling at wanted to keep you moving forwards mate yes, the seat belt stopped you from flying through the windscreen.
@@KarlGosling so the car decelerates it pushes me forward into the seat belts and if the car exelerates it pushes me backwards into the seat .
Good night dear Karl ,
Of course when your car goes forward you never go backwards.
However, excuse me if I'm not agreed with you,
in simulation is exactly the opposite, in simulation we do not want to simulate what the car do, we want to simulate the sensations of driving a high speed car.
So, in real life when you accelerate, in a fraction of second you have the sensation to stay behind because the seat is pushing you, in simulation you go backward and your eyes and brain make the rest of the trick.
In real life when you brake, in a fraction of second you have the sensation to go forward because the car brakes before your body, besides if you haven't a seat belt for sure you go through the windshield,
in simulation you go forward and if you have a multiple point harnesses secured in a place outside the motion system it will be the best sensation.
Thank you, all good to you,
happy new year
Ps. I'm sorry for my Google english
In simulation we DO want to simulate what the car does in real life, this is the point of simulation.
If you reverse the directions (Forward/backward) it feels totally wrong... would you also swap left and right when turning if you had a front actuator, no?!
English translation is very good, thank you. :)
Sorry from me to Karl...... but Yes!! we do want to Simulate the FEELING!.
But what you do is copy/replicate the physics which is impossible or....( your surge platform would be 1200mtrs long 😉🤣😂)
@@KarlGosling
btw i hope you are getting more curious now😉😄
Yep I've tried both and I definitely prefer it the opposite of the "right way" that Karl thinks. I use vr though
so many people don't grasp the fact that speed is only relative , there is no absolute speed, this is not existent in the whole universe. but most of the time we do implicitly refer to the speed relative to the ground.
But to understant properly how motion rig works you really need to understand that.
But Karl. The Batmobile does exist. 😂.
All jokes aside, basic Newtonian physics.
I mean its just inertia right? In stargate SG1 the space ships had inertia dampeners.
Ha ha, love this discussion, so i am driving a van, in the back of my van i have unsecured item of furniature, when i accelerate the item goes backwards, or does it stay where it is until the back door makes contact? under braking the opposite happens.
It stays in place (relative to Earth), until the back door makes contact. Note, that's assuming your furniture and floor are perfectly slippery (the grip of the floor would accelerate the furniture, just not as much as the vehicle if the furniture slides). Your furniture is moving backwards relative to the vehicle, but not the Earth - that's just because of where you're viewing it from. It would be like driving in your car, looking out the window and saying "the trees are going backwards" - the trees aren't moving (relative to Earth), you're observing from a moving vehicle.
Another example is pulling a tablecloth so fast the plates and glasses don't move. If you were a lego-sized person holding on to the tablecloth, the glasses look like they're going backwards, when in truth you're going forwards and the glasses haven't moved (relative to the table/Earth).
Exactly as above yes! The van has moved forward and your item of furniture is in the same place (or a little further FORWARD).
I love this , karl. hehe
lol Thanks!
If people would actually READ the laws of motion. Something at rest tends to stay at rest until acted upon. The sensation of “moving” back is that transition gap between rest and said object equalizing movement of the object applying force (car) and the object at rest (person.
I think you need to have a weekly live Q and A session ❤
Easiest way to grasp this. Is very simple.
Get in a real car, hit the loud pedal, which way does your head want to go, yep, it goes backwards. So to emulate that with surge, the seat need to go forward. I struggle to understand why people don’t see this as being correct. ?
Not wishing to be pedantic Karl but at 5.37 in the video who was driving? Batman or Robin?
Pretty certain Batman... but who really knows?! lol
Hi Karl I’m really missing you mate. I’m hoping you are ok. Take care of yourself.
I've been unwell for a few weeks but will be back at it very soon! Thanks for your thoughts.
I can see that, if i have surge working that way, forwards for acc and backwords for brake and at the same time having the seat leaning forward in breaking and pushing you in to your seatbelts and accelerating leaning backwards, giving you even more sensation of acc and braking, i dont know will find out when i get my diy motion up and running :).
Tilting like that is ok as the whole rig is also moving in the correct direction too, like a FWD picking up at the front under acceleration or a RWD squatting down.
You don’t recognize the forward pitch on braking or backward pitch on acceleration because your eyes are telling you the car isn’t pitching ( barely ), rather your back is feeling pressure from the seat (pitch up) or your hands pressure from the wheel and chest from the belts (pitch down). Your brain thinks there are gforces present. Works beautifully especially with well tuned surge sled coordination. Motion compensated VR sells this illusion much better than triples as it hides your room environment from your peripheral vision.
@@imagebuff thats true and right if we are talking about a race car or a new car, but for me that run 500 dollar shit buckets from the 90ish with worn suspension, there like a boat and you definitely get the car moving alot on breaking and acceleration and cornering, same with you in the car is flooping about in the seat, so if you are simulating a old car or for like me i want it to feel like my old cars i feel like both a rig that moves alot and a seat mover is realistic.
Quick question off topic Karl
Asetek forte or invicta base
Or simucube 2 pro
And then
Forte or invicta pedals or alternative lol 😂
Forte is plenty for most (more refined than the Simucube base) and the pedals also mate... Invicta is for money no object sim racers IMO.
What kind of cro-magnon actually needs this explained to them?
What kind of cromagnon feel it needs to be explained?
It's pretty simple, when a car goes forward, you get pulled into the seat (hence go backwards feeling).
Nobody is wrong here... just a bunch of meatheads arguing semantics
@@GregoryShtevenshNope, it’s not just semantics. Being pulled into the seat is not at all the same as the seat being pushed into you. With the former the force is being applied to the front of your body, and the latter the force is being applied to your back. They are literally opposite forces.
@@GregoryShtevenshsorry mate but I think you got the whole explanation wrong. You are never pulled onto your seat. You are always stationary body in space. You travel through space as everything else in space meaning the earth that we are standing on. So when the car moves you just move after the car and that's the sensation you're feeling, falling onto the seat will be a more accurate representation of the experience you are feeling at that moment in time 🥸
This video opens up an endless range of content for you, content creators. For now, explain to me what happens to the body when we turn right, I'm not sure.🤣
Can you imagine motion users having the left and right round the other way as some think forward and reverse should be?! lol
How much difference is there between entry level Direct Drive Wheel base and a top one?
Pretty big mate, power, response, quality.
If youre accelerating in the same direction as the earths rotation you would be travelling backwards 😂😂- Carl im only messing , Great video again
lol! Thanks mate!
ok it makes sense
Isaac Newton discovering physics be like
Indeed!
You seen that Boosted Media video on EA WRC triple screen "fix"? (not a proper fix but may be worth a fiddle)
I have mate but will wait proper support.
@@KarlGosling Yeahs it's still pants. Fingers crossed!
Hiya Karl will you be reviewing the new GT omega CHASE and INERTIA seats?
I have them both here now!
makes sense.
Actually you are all correct.... and all wrong! The missing word here is, .... RELATIVE! If you fall asleep, then wake up in the passenger seat with a blindfold on, it is impossible to know whether the car is accelerating forwards , or decelerating in reverse. In both cases you are pushed back , relative to you looking forwards, in to your seat! If you wake up at a constant speed, in a plane, it is impossible to know the motion if any ,of the plane, if you dont have a frame of reference, ie a window
Yes and thankfully most of us are not asleep when sim racing! lol
Could you do a vid on the new GT Omega bucket seats pls thxs in advance
I have them bot here now so not long to wait!
I think some people think you go backwards when you get pushed in to the seat when you do a fast pull off but thats not at all how it works as your still moving forward with the car, you are just moving slower than the car so the seat is pushing in to you not you pushing in to the seat, but for some people basic physics is hard, get on a bus opr train and jump yopu will move with with it.
Spot on mate yes!
They might be struggling to explain the G forces at play when accelerating forwards in a car. But they might not understand the effects of G forces when you're in a car, accelerating, braking and cornering. Either way it's funny and forgiving if that is the case.
But if they genuinely refuse to accept what has already been observed and researched by scientists and universities, its not worth the time and energy to argue with them daily.
F150 rear ended by school bus in eighties. Mom had whiplash, 'head rests' were ... poor.
Yeah ouch!
I can't believe you had to make this video lol.
I know! lol
Oh the fact that this video needs to be a thing our education system has failed us 🤦
Good explanation! I hadn't really thought this through before, so this was educational.
After thinking about it for a while theres one thing I'm not agreeing with though! Why should'nt you pull the cockpit back for braking?
The less scientific reasoning:
simply look at the video of how the bodies react to both acceleration and braking. Why would it be realistic to only simulate how your body reacts to acceleration and not at all simulate how your body reacts to braking?
If you *would* pull the cockpit back during braking, wouldnt it look and feel the same as the video during braking? I think it would. So why leave that half out?
Alternative semi-scientific explanation:
the rig isnt a car, it is simulating the car by moving in a way that applies the the relative forces a car would exert on you... And the the surge actuator part has the potential to do this for *all* accelerative and decelerative forces. (temporarily atleast, but we'll get to that later)
This means it is perfectly fine to move the rig backwards to simulate braking. It is just simulating the "delta" between the cars movement (acceleration or deceleration) and your body - regardless of if the virtual car is moving forwards or backwards. Again, it's not a car restricted to a short track, it is simulating the car :)
...
Also, this video really has made me question how useful a motion rig like this can really be...
After all, the simulation of acceleration can only be sustained for what, a couple of tenths of a second?
So you could never have that proper "pushed into your seat" feeling really for more than a jolt unless I'm missing something obvious? Ive never driven a rig like that so I wonder how much it would actually add for me personally. (I am not dismissing it though without experience!!)
Makes you wonder if inflating the seat and neck support to push it into your back could simulate constant acceleration to some degree though? :) (especially if using belts)
You can pitch the rig backwards to simulate a bit of constant acceleration g force. It works as long as the visuals don't portray the pitch move. Requires motion compensated VR or flat screens moving with you in a dark room.
Just because it would feel like you are reversing, this is of course whats happening.. but you can have your rig do that if you like, I just don't as it feels odd to me.
@@KarlGosling Its ofcourse all up to you, but from a pure forces perspective applied to your body, my point is that pulling the rig backwards to simulate braking is equally correct as for example pulling the rig backwards when reversing from a stop, as you do now:
If you'd shut your eyes, *you could not feel a difference* between reversing from a standstill or braking from a steady speed. The forces applied to you is the same. Therefore it makes sense that your rig should simulate both theese forces. (It will simply simulate the forces on you, due to the inertia between you and the simulated car)
The reason it feels like youre being pushed backwards now (if you enable pushing the rig back for braking) is probably because you can *see* your monitors moving away, which is a fair point.
But on the other hand, moving closer to your monitors when accelerating could be argued to be technically equally wrong, and it seems youre fine with that :)
@@imagebuff Yeah, as I recall the Force Dynamics rigs does this for example :)
The fundamental problem I see with this, is that when you want to increase side G-forces, the felt regular gravity will decrease instead: When taken at the theoretical extreme, at one G of side load you'd feel no gravity :)
Also, really needs fast rotation to be effective...
And it needs a well calibrated center of rotation!
I still wonder if you'd feel some strange inertia effects of the rotation in your limbs though?
@@rogerwennstrom6677 I agree it's not perfect but given the error in our rig gear and the infinite differences in one tune to the next it's a very effective method.
It's too early for this shit. 😵
To much for Tuesday mate 🤣
Sorry! lol
I had a very good friend who was convinced that as a skydiver pulls his rip cord he travelled up. I tried really hard to explain but I guess his brain was defective. Just giggle discreetly Karl but don't let 'em see you.
Thats another perfect example I've heard too mate!
The exact same people think that when you open your parachute after jumping out of a plane you suddenly start travelling upwards… 😂
hahahaha this is also VERY true!!
All I will say is stand up in the back of a sprinter van at the bulk head and ask your friend to put his foot to the floor
Let me know where you end up lol 😂
I understand what your saying though 😂
The van moves forward... I fall over and because the van is accelerating faster than me I slide to the back! lol
@@KarlGoslingexactly lol
I’m in agreement with you by the way just read my message back to myself and realised it could be read the wrong way pmsl 🤣
Few beers 🍺
No excuse haha
@@KarlGoslingtry standing in it after a few beers lol 😂
This all has to go with inertia ultimately. I love all of your videos Karl and have nothing but respect for you and all of the content you create but I'm at a loss with this one. Perhaps the most simple test you can do is to go and drive a real car, brake as hard as possible from high speed and see what happens, you will be thrown forward. Vice versa with acceleration. Granted these sensations are almost invisible at normal road speeds but we will agree to disagree on this one. I'm not here to argue and you are and will always be one of my favourite CZcamsrs and a brilliant guy in general.
It's all good mate!
its called COG on a ball
Jump in tje passenger side of my LS3 manual Commodore, and let me show you what being pulled into your seat feels like. This is 100% how it works lol.
Edit: you're not pushed backwards, but you're pulled backwards into the seat is a better way to explain it. Its not magic lol... that's inertia
You are not pulled at all, what by?! lol The seat PUSHES into you as it accelerates forward along with the rest of your car mate :)
There are 2 scenarios where that statement can be considered true. One is with addition "Relative to the vehicle". Second is with addition "relative to the space if you accelerate against the rotation of planet"
Batman isn't moving backwards. His car is accelerating faster than his body until his body and head are pressed up against the seat.
When batman brakes his car is decelerating faster than his body, so he keeps moving forward.
People who don't get this must be trolling.
Spot on mate!
Slow news day Karl? Couldn't find something to review? Don't take this the wrong way but I didn't have this channel down as babys first science lesson.
Nope, needs must apparently mate, it's what the comments asked for.
Myth BUSTED!
This is a troll video right? Please tell me this is some sort of trolling thingy
I only wish mate, genuine confusion and comments.
@@KarlGosling all i can say is wow🙈
No no no NO. The planet revolves under you car whilst the car remains stationary. Well technically it doesn't revolve as everyone knows it's a 26000 KM2 flat plain.
Spot on mate, in fact it's all our car wheels that are in fact rotating the earth... if it wasn't flat of course.
its called drag bro
When you accelerate hard in a car, you're pushed back into your seat from G forces. Having the sim seat shove you from behind achieves the same sensation. When you brake hard your torso is thrown forward, hinged at the waist, when the sim seat jerks backward your torso is thrown forward. So that is the correct way to do it
No mate you are not pushed back by G force you are always pushed forward (gravity just wants to keep you on the spot) and again when braking you are never "thrown forward" you are already moving forward and begin to slow down to match the new reduced speed of the car... this is momentum.
Technically correct but he's describing what he feels and that is what the rig tries to reproduce. We have to trick the mind.@@KarlGosling
Karl Gosling: Simracer, CZcamsr, and newton laws follower. Sounds like a cultleader…
Yes. When you hit the gas pedal in a reall car the Gforce or force of gravity pushes you back in your seat. Braking will push you forward because of the negative gforce. Hence the requirement of seat belts as a safety feature.
You are right but semantically wrong. G force is not the force of gravity. It is the ratio of the force applied divided by the force gravity. This just lets you have a sense of the magnitude of the force. The car accelerating is the force that is applied. This acceleration could be from speeding up, breaking, or turning.
To keep it short, no mate.
Really? This needed a video ? 😂
Apparently so yes! lol
Weight = mass x -g-force,…..negative….positive… wait, this sounds like school work. Yuck!
If you want motion to replicate what the driver experiences, then the rig moves forward on braking.
If you want motion to replicate the movement of the car, then the rig goes backward on braking
Option 1 only if it's a helium balloon (or similar) driving the car.
Option 2 is the only correct way in both situations. During heavy breaking of a real vehicle, you'll be "pushed" into the harness.
The person is sat in the rig. The rig is the car in this situation. Option 1 will never be correct.
Neither option is correct.
As @tabs1913 says... your rig is your CAR, you are the driver so the rig must simulate what the car would do in real life, you are not sat on/in another driver and your car never goes backwards when braking! lol
You are making it worst 🤦🏻♂ This video shows you completely mis-understood this topic (or even motion). Sorry!
I think maybe you mis-understand mate? I know exactly what my car does when I accelerate and my simulated car (rig) does exactly the same... it's really simple :)
You both are saying the same thing from diferent perspective!
@@KarlGosling That's the problem, you keep trying to simulate what your "car does", instead of how you "feel" when your car (not your rig) is in motion.
This is almost as funny as you debunking the pedal travel sim racing myth. Where did this rubbish come from. Please do why you don't actually need to use 100% FFB on your wheelbase like is current wisdom and why you actually shouldn't next. Hint I don't need to have the dynamic range necessary to wreck my wrists ;-)
Are people really saying we should use 100% FFB?! Surely not?! lol
@@KarlGosling they say it's best if you do on the base and then turn it down in sim per car.
I've never heard a man describing inertia in such a tedious boring way.
Get a childs pull along wooden train, place a metal ball bearing in it, then pull the train and see what the ball does.
You'll save 21:58 of your life.
I wasn't explaining inertia and you've missed the point of the video! lol
But the train and ball bearing would help demonstrate how we are independent of our cars... to an extent.
@@KarlGosling I like you Karl, I really do, you put out some fantastic media. But I really think inertia is beyond you. Take care.
you are either 100% ignroing g-force. or explaining this very badly.
the rig IMO has no reason to move forwards and backwards.. But tilting up and down to emulate G-force is better
What do you call the force that you experience while under acceleration?
Nope he's absolutely correct, as the car accelerates your body attempts to stay still, effectively trying to push the seat through you. you experience G LOADING until you and the seat are matching velocity.
Simply put it's a velocity differential apparent until the car and your velocities both match...
@@SRS13Rastus no i agree with his point, i dont think he is explaining it well. using terms like "forwards, backwards, and pushing" arent really useful here.
I'm doing neither but I understand if you don't understand how I've tried to explain it mate.
If your rig can move forwards and backwards just as your car does under acceleration then it should do so... otherwise why have a surge actuator at all?! Tilting up and down generates NO acceleration, a surge actuator does and it feels like it too! :D
Why not both? Combined 😉
For people that got the whole explanation wrong. You are never pulled onto your seat. You are always stationary body in space without a massive object nearby, you will never experience the Sensation of speed. The feeling of speed is the feeling you get apply by a centrifugal force. You travel through space as everything else in space meaning the earth that we are standing on. So when the car moves you just move after the car and that's the sensation you're feeling, falling onto the seat will be a more accurate representation of the experience you are feeling at that moment in time 🥸
