I don't charge anyone to watch my videos, so please donate if you can to keep me going! bit.ly/scienceshortsdonate
me: thinking i know enough
also me: realizes i havent even finished the intro...😂
Thank you very much your clarrified many concepts dt l ddnt understand in class . You are a blessing to me
1 in the morning before my 8am physics unit one, pray for me
same, pray for me, i got my A-level exams in 4 years time...
Kuznetsov Maths 4 years? wtf. we do 7 subjects in 2 years
So how did you do in your exams?🙃
I have al today at 8 physics unit 1
@@mohammadakram8518 ummmm, a d in physics but I'm working on it. Retaking to get a c and my other grades will be good enough
Your channel is amazing, thanks a lot.
Excellently done it..
I got stucked in this concept everytime.
Great video. I find these a really useful resource to share with students.
Thank you
This really helps thank you so much.
Your videos are really useful Thanks!
Brilliant video a question on this topic was in my past paper and I never saw it before cause it’s not in our book and our teacher didn’t mention it, so thanks
Nice one I need the lesson of up thrust and tension for my exam
Thankx a lot, i was struggling a lot w this topic❤
LIFE SAVER !!! YOU HAVE SAVEDD MY LIFE DUDEEE
Thank you!!
amazing man .Keep it up please.
great physics teacher!
Thanks a lot🙋♂️
I just want to let you know that you added this video to the M&M playlist twice haha
Well explained
NICE!
Thnx so helpful
Less goo paper 2 physics today at 3 (I’m so screwed) but this video helped loads
Assuming the rubber ducky is a perfect sphere of uniform density...
we had spherical cows in physics...
Please explain Plancks quantum theory
So what does it mean if the object is only partially submerged in the water?
Bros the 🐐
Nice
Thanks a lot sir.
2 hours before actual paper 2. shoot! did not cover this in class, but blame myself for not looking at it sooner myself
Ok, turns out this wasn't for my course anyway :)
@@matthewbriggs2805 😂😂
is this in the current aqa spec???
Based on this question came in jee 2013 paper
Love and thanks from India🇮🇳🇮🇳🙏🙏
Bro ab ap Konse college mein parh rhe ho ?
Note: there may not be always upthrust for example while something is falling without parachutes or something like that
🙄
@@ScienceShorts srry if it interrupts
You haven't done the required practical on investigating the terminal velocity of an object in a fluid (eg a viscous liquid)
2 dimension momentum pls
mahmoud 11 yesss pls
Update, went terrible but it went terrible for everyone and I knew this part?
what exam boards are your videos made for? I do OCR A x
I have a question. Is it important for the ball to float for U = W or can it be in the center of the water or even at the bottom?
according to what he said the ball must be stationary, therefore i believe it can be located anywhere in the fluid so long as it has no motion whatsoever
take into account newtons first law of motion when saying that U = W, if U = W that means that the ball is in equilibrium and that there is no net forces acting on it, therefore (provided that no external forces act upon it) the ball will remain at rest or stationary.
BUT
later in the video he states that in order for U to = W, the density of the object and the fluid must also be the same. Therefore, with the ball being a solid object and the water being a liquid, their densities differ and therefore the ball shall not be stationary everywhere because it will not be in true equilibrium without external forces acting upon it
(keep in mind that I am just a student so this might turn out to be wrong but I think that my evidence holds)
cheers fam
np bruv
Are you a teacher in the uk
what ifthe drag force is negligible ??
Please describe stokes law in more detail
You wouldnt be able to do an example of a item like dirt particle settling in water?
Ur voice is hot wish I had a physics teacher like this irl ;) sry fir being a creep but I hope these videos help me get an A this may lord help me
😂😂😂😂😂👏lel
@@kennethjoseph8360 xD
Did you get an A?
I was taught that if u=w then the object floats
My dog stepped on a bee
pls continue
Thank you so much I have been struggling and tempted to quit😭
Can you please add this video to the mechanics and materials playlist. Thanks!
Done - thanks! 😊
@@ScienceShorts This is for other exam boards right, not AQA? cos ive never been told anything about this? i might cry if i have to learn this for monday
@@ImadAl1 lol same situation but i checked the spec and i can't see it there
@@chinmayvashishtha alright thanks, i think im screwed anyway without having to learn this😭🤣🤣 i never learn always leave till last minute still got 3 days to get some practice in never give up
@@ImadAl1 how did your exam go ?
Pleaseeeeeeee solve more paper 5 CIE....I'm begging u
Please I need help.
The three forces acting on a hot ball moving vertically are its weight, force due to air resistance and upthrust force.
The hot ball descends vertically at a constant speed. The force due to air resistance is F
Which weight of material must be released from the balloon so that it ascends with the same constant speed.
A. F
B. 2F
C. 3F
D. 4F

@@ScienceShorts where how?
Link in description.
what does the v in pvg mean ?
Volume 😊
Oops no tension
:)
Hope ma exam goes well 😭😭😭
you are such a fool

I have physics paper3 tomorrow wish me luck
Same bro
