Extraordinary making.....sir. we are awaiting your subjective presentation or explanation sir. Thank you so much sir. Really cool and in-depth working sir..
@ 4:34 The total force on ONLY ONE SIDE OF THE BOX, assuming there are N particles pushing on that side, at the same time. What about the other sides? Don't they feel any pressure? In my opinion, the pressure in a box is equally spread throughout the box. @ 6:28 Only 1/3N is hitting one side of the box.
In physics every collision is actually elastic. Inelastic collisions are simply classical mechanics' way of approximating collisions of large, macroscopic bodies. In this model, the bodies colliding are particles or molecules. Every collision is elastic. No exceptions.
Yes Youssef, you are correct. It is the average, (i.e. the sum of the averages), of the square of the velocity in each of the three directions (dimensions) x, y and z.
Question, How come we use delta P = 2 mVx , and the V here is for velocity then you used v= x/t where V here stands for speed not velocity and took its valuue to plug it in the delta P = 2 mvx . explanation please?
deltaP=2mVx and V=deltaD/deltaT where v is still velocity, D is distance, and T is time. Velocity is a vector and has a direction where as speed does not. Speed is distance divided by time where velocity is change in distance over change in time.
he later used the 3 dimensional model assuming the particle velocity to be the same in all directions. Knowing the actual velocity of every particle is impossible but that is why we have averages
It’s not a calculation, it is a derivation. And it is not right, and it is not wrong. This derivation is used as (represents) a scientific model for the kinetic theory of gases. And is very useful to help understand the basic principles of gas dynamics, and the relationship between the macroscopic and microscopic properties of matter (at least in chemistry, anyway). Bet you’re a physicist. 🥸

Thanks so much! This was probably the clearest explanation I've seen!
Good job! This is clear and straightforward. Thanks a bunch! Your gift to the world of physics and chemistry learning is appreciated.
great video man, really a shame you don't have more support
Love from Pakistan ..great job sir
Great Video! Clearly explained, if you're not a teacher, you should be!
Great video 👍👍my all confusions are gone ☺☺😊Thank you so much 😊😊
It is so amazing to see you redrew cube diagram many times to make it appear on new papers!
It is a superb explanation, perfectly paced.
Best way of explanation I've seen on this one.
Very well explained. Please make videos on thermodynamics II
👏🏻 bravo, that was fantastic, such a clear explanation
Extraordinary making.....sir. we are awaiting your subjective presentation or explanation sir. Thank you so much sir. Really cool and in-depth working sir..
Omg, Thank you, trying to find a good explanation for long time!
Awesome! So clear.
I don’t understand why people give a thousand likes on videos that are useless but care less when it comes to important useful stuff
Well done
Thank you sir ♡ i will always be grateful to you ♡ oh god he saved me

Very clear video thank you. Put can you explain why you assumed the collision is completely elastic ?
In physics every collision is actually elastic. Inelastic collisions are simply classical mechanics' way of approximating collisions of large, macroscopic bodies. In this model, the bodies colliding are particles or molecules. Every collision is elastic. No exceptions.
At 5:45 shouldn't the v^2 have a line above it, signifying it is the average of v^2?
Yes Youssef, you are correct. It is the average, (i.e. the sum of the averages), of the square of the velocity in each of the three directions (dimensions) x, y and z.
acc to definition,delta t stands for the time to change the momentum,so why dont we take the impact time ? pls explain.
Same question. Have you found the answer?
nice explanation :)
Thank you very much Sir.
5:00 why this volume is a cube?
Thanks!

In college you all will understand (hopefully) that this calculation just is NOT RIGHT.
Why is it not right?
