You kinda sound like you‘ve given up on life and that fits talking about maths so well
kinda sad
I havent touched mechanics in months and it feels like i relearnt everything in under an hour
Glad you found it useful
me asf
In the same spot as you a year later my exams tomorrow it’s 11pm rn 💀
@@guobaaa good luck, hope you do well
@@DoubleAAce THANK YOU SO MUCH IM COOKED I BARELY DID MECHANICS IMMA DO MORE IN THE MORNING convincing myself it is common sense
Exam tmrw and done 0 revision, Thanks!!
Good luck! Let me know how it goes, you’ve got this
same here mate
Try the morning before with zero revision 😂
@@sirobi2524 me frfr
We've got this team 💪
the last line of defense is the 100% completion of the stats and mechanics for my grade... that being said nobody in our class ever paid attention to this topic so me and this video will be cooking deliciously :muscle:
You have got this 💪 keep pushing!
throughout heaven and earth, i alone am the cooked one 💯 💯fr tho this helped a lot, at least ill have the luxury of maybe passing with a C, god has something special in store for those generous enough to bring down the grade boundary amen
@@jakit0556 who knows you might have done better than you think
Exam in 2hrs and im learning content
Youve got this!
absolute godsend - thank you ! i can't wait for this last week to be over
You are welcome! You will nail it I am sure, good luck 👍
me too
You are a life saver
Watch your video 2hr before my exam saved my marks
I'm glad it helped you! Fingers crossed for the results
doing it right now ive got maths mock in under 2 hours
You are honestly such an icon, Sir. I genuinely love and appreciate you so much. I will be acing that mechanics test tomorrow!
Things you love to hear
watching this x2 speed exams in exactly 1 hour thx a lot for this
Same here bro 😂 no prior revision except this morning. We got this
FRR LMFAO SO FINISHED I TRIED GOING OVER HYPOTHESIS YESTERDAY AND TODAY
goodluck we acc cooking this exam
You got this! Good luck 🤞 let me know how it goes
You're a lifesaver, thank you so much, just subscribed. Cannot wait for this week to be over tho
Thank you glad you enjoyed! Good luck for this week!
seriously thank you so much absolute lifesaver
You are welcome! Glad you found it useful! Would appreciate a sub and a like. Tune in for a reaction video tonight/tomorrow
38:29 nahhhhhhh your the legend sir not all hero’s wear capes I wish I had during my whole 2 years !!!!!!!!!
Thanks for the full last-minute revision. It was very helpful !!
Glad it helped! Good luck for your exam
It's all done now! Paper wasn't that bad, to be honest, but statistics was a bit crazy.
@@alistonreginold3812 well done! Haven't seen it yet unfortunately
Mate you're absolutely brilliant, perfect pace so I can do the questions with u and see any mistakes I made. Edit: At the end now that was unbelievably useful feel bad on past years that didnt get this
Watched your vids morning bedore, no prior revision and feeling confident. Thanks a lot!
Glad to hear it! Good luck 🍀 let me know how it goes
What a goat🐐 do one for stats but maybe a vid specifically on hypothesis (different types?)Thanks very much for this.
I'm going to do one like this one on stats, then maybe hypothesis testing would be a good one, if I can fit it in I'll do it
lovely stuff ready for tuesday
actually made me understand so much better thanks cher!!
I'm glad it helped! I recommend my integration video next as it's a large proportion of the A-Level
@@DrJamesMaths ok, i will watch it thanks!
so thankful I came across this video
We always come through here!
my al is in 7 days and this couldn't be more helpful
Glad it was useful! Share it with a friend... Or 100 👀
Tysm king🐐🐐🐐
You are welcome! Good luck for tomorrow
YOU’RE A LIFE SAVER!
I’ve just watched 15 minutes of this to realise that this is for a level maths and not a level physics
Is that a good or a bad thing?
Got my paper 2 on Tuesday so thank you for this!
No worries! Good luck with it
watched it in 2x speed. exam in 1 hour 😬
How did it go?.
@@DrJamesMaths mechanics section was great. honestly think you saved my grade
@@whupass you are welcome! Glad it went well
1 hour left until the exam, im learning this😭😭
You've got this 💪 let me know how it goes
You’re a legend
I appreciate it! But the videos only been out 10 minutes can’t have even seen it all 😂
@@DrJamesMaths unit
@@DrJamesMathsthe title is enough sir 🙏🙏
Thankyouuuu !!
you made it so easy thank you so much
Glad you found it useful, let me know how it goes
Will you be doing another video for statistics? Also thanks so much for your other video. Saved my life for paper 2
Glad the last video helped! Will try and do stats tomorrow, no promises! But that's the aim
the hero we needed but didn't deserve
You guys deserve it, you came looking that's the first step. I'm sure there are plenty of people who aren't even revising right now
this is so helpful thank you !!!!!!!
Glad you found it useful! Let me know how tomorrow goes! Good luck
Could you do one for Statistics would be much appreciated!!
The aim is tomorrow for stats, but no promises
It’s live go go go
@@DrJamesMaths ty SO MUCH
I'll be writing my exams next October, so I still have time. I was wondering if watching and learning from the video is enough to answer atleast a few question from past papers?
I would recommend watching the pure and statistics videos as well. But they will definitely improve your understanding
@@DrJamesMaths OK thanks and will do 👍🏻
😢😂 tomorrow is mechanics exam 😅😅 need luck 🍀
🤞🤞🤞 sending every bit of luck your way
@@DrJamesMaths your luck counts mr James🙏
Exam after 45 mins I'm cooked
@@sc4rydude277 you got this 🤞
Mate im cooked but this is making me more of medium rare than a well done. Cheers man
You are welcome! You've got this 💪 let me know how tomorrow goes
Thanks
Oh my! Thank you so much 😊 I'm glad it helped you out!!
thanks lad
Always a pleasure
make a stats one too
would be helpful
Will try and do it tomorrow, no promises! But that's the aim
Please do as pure and stats and mechanics
i love you bro
Thanks, why did you substitute 3 at 11:45 isn’t U=3
nice video, just subscribed! could you recommend a good site/anything to find more challenging practice questions?
Thanks for the sub! Specimen papers are sometimes quite tricky have a go at those
Also naiker Maths is a great website for topic by topic past paper questions
@@DrJamesMathsi got into durham cuz of you thanks!
Love to hear this! But you did the hard work not me! What are you studying?
@44:29, what did you punch into your calculator to get t=1.84 & t=-0.277 ?
Solved the quadratic, using the equation function on the calculator but you can use the quadratic formula
At 22:57 part b could we also have started straight away by converting the resultant force into the magnitude using Pythagoras and then continue with the question as normalso that we automatically end up with the acceleration magnitude?
Yes definitely
@@DrJamesMathsthanks sir, great video for a quick recap!
I wish I had the mental aptitude for science and math.
With hard work I'm sure you can get it!
Hi at 11.20s instead of using integration can we use the formula for a which is v minus u divided by t and obtain velocity?
No because v-u/t only applies when it is constant acceleration which it isn't in this question
im so cooked idk how to cover everything for tomorrow
double speed every video that might be the play for us BOTH
You got this 💪
i hope it gows well
Me too, good luck 🤞 let me know how it goes
🙏🏻
goated
Thank you, glad you found it useful!
u legend
I try 🤣 Let me know how it goes
legendary
Glad you think so! Would appreciate it if you subbed and shared with friends! Good luck for tomorrow
@@DrJamesMaths Thanks!
vectors is not in syllabus right? f or m1 its not written in the cie 9709 24 syllabus
Not in the cie explicitly but you need to use them with forces and it's in the pure section of the syllabus
Thank you, what changes when the moment question involves drums and hinges
The reaction forces change with a hinge
can I follow your videos for OCR Maths?
Absolutely!
@@DrJamesMaths awesome thanks
im watching this like my exam isn't in 90 mins😭
i NEEEDED THIS my exam is in 3 hours and i havent revised and i know nothing 😅
Well Bob, now you know everything
@@DrJamesMaths your stats one is on my screen now you are a LIFESAVER
curious as to how your exam went haha@@boblmao2915
At 42:46 shouldn't the displacement be positive and the acceleration negative or vice versa?
You can take which ever direction you like to be positive as long as you are consistent
i might actually get to uni
dont stress man
@LukeLifts bro I've had 6/8 papers, I only feel that 3 of them went well(all econ), maths paper 2 was shocking, so demoralising for me
@@Ziyanasto you got this!
@@Ziyanasto I'm in the same boat as you. Maths Paper one was lovely but completely blind-sighted on paper 2. All to play for with paper 3!
@@IkinAaron paper 3 was a stinker time to look for backups
52:41 how come you don’t use 609 as the clockwise force as well
Because I was taking moments about A so the distance is zero therefore the moment is zero
@@DrJamesMaths ohhh that makes sense I was stuck on that part of moments for a while, thanks
what’s wrong with final 10min? It’s my iPad problem or it’s just 240p😂
Please try do this for stats too yr1 and yr2 thanks
Im going to try
@@DrJamesMaths Thank you 🐐!
@@saidbenrahma9129 stop begging it G
clutch
Glad you found this video! Let me know how is goes!
how do we know what amount of significant figures to leave answers to ? you only leave it to 2 s f if g is involved.
So g for most exam boards they use 9.8 but final answers normally it will say, if it doesn't say check the front of the exam paper, it often says 3 SF unless stated otherwise.
I need to lesnr all this and year 2 stats by Thursday ☠️what do you reckon I do ? I’m thinking do projectiles and all of year 2 stats
Use my three videos on Alevel applied, that will get you to B if you use them properly. Then smash loads of questions
@@DrJamesMaths so the stats and mechanics videos. What’s the 3rd one ?
This one: czcams.com/video/VQXXJnZdpCo/video.htmlsi=qi1n-mlZA_rwTgdr
@@DrJamesMaths whete do you recommend I find the questions from? I’m thinking going on savemyesams and doing questions on that
Woooooo
for example 1 in moments section is the child also meant to have a reaction force?
No, so this is a common mistake, the reaction forces come from the supports, so R1 and R2 are different because the child is stood on the rod
@@DrJamesMathswhy doesn’t the child have a reaction force?
@@Rielle5222 ^^^
@@DrJamesMaths ohh sorry I completely skipped over that😭😭
Is this for Cambridge or Edexcel??
Lots of overlap so both but mainly Edexcel
holy shit...
Yes?
Can you cover work, power & energy?
Further maths mechanics?
@@DrJamesMaths Both maths and further maths for CAIE exam board
I need this too pleaseeee
edexcel?
Works for all!
52:34 I took moments from B and got 1.35 for x is that also a right answer
No because it’s asking for the distance AC. I would always take your moments from the position which suits the question best. In this case A.
@@willbird8727oh I ain’t read the question properly thanks
I still don't understand clockwise and anticlockwise for moments.
Imagine putting a pin in where you are taking moments from. Then all the forces that would turn the rod clockwise (are the clockwise moments) and all the forces that would turn the rod anticlockwise (are the anticlockwise moments). I hope that makes sense
wait I thought in mechanics they say gravity is 10m/s squared and not 9.8?
Depends on the exam board most of the exam boards use 9.8 it should say on the front of your exam
@@DrJamesMaths 🙌👍
Is this for cambridge board cies???
It covers most exam boards as there is lots of overlap, but I can't promise it covers everything in the Cambridge cies board
OK thank you
Can U plz suggest another video like this that covers all the mechanics topics.. like a crash course video??cuz I'm a caie student and I have my mechanics exam in a few days and I'm really stressed about it 😢 6:26
@@machacooling so I just looked at your syllabus and all you need is this video plus a video on work, power and energy (there are loads) and momentum (again there are loads) these topics are covered in A-Level physics so might be better to go that route
exam in 50 min 😭😭😖💀💀💀💀
Good luck!! 🤞🤞 Let me know how it goes, hopefully this video helped
it was SO damn difficult but the time spent watching your video was time well spent. 😇I will be forever grateful. lets hope for the best🙌@@DrJamesMaths
@@DrJamesMaths The time spent watching this video was time well spent 😇and i will be forever grateful. The paper tho was absolute nightmare....especially the last question! Lets hope for the best🙌
@@hehehehahahahihi I'm glad it was helpful 👍 I'm sure it turned out better than you think
stats & mechanics is tomorrow im praying this saves me 🙏
You got this 💪 let me know how it goes
exam tommror im cooked
couldn't sound more miserable if you tried.
🙃
Exam is at 1:30 and I’ve watched this video twice now. Huge help. 🫡
