At 4:26 how did those frictional forces become an action reaction pair? Because action-reaction pairs only exist between a system of two bodies, but we involved two systems of two bodies each
While solving the problem as single system, that friction thing can be considered as action pair....but if u choose to go separately then it's not a pair at all which u hv asked....so it's there when u go individually n that's why he has shown it 2 rimes in both the bodies
The technology is a lightboard. You can find out information about how lightboards work (and how to build your own) here: lightboard.info/. The technology used in the MIT Lightboard interactively flips the image and adds auxiliary images and video inputs into the captured video in real time, so that the instructor can immediately review the footage.

the best explaining ever. your solution is very organized and simplifies the situation. thanks a lot!
Dang, so clear, thank you a billion!
Really great explanation! thank you so much!
Really is the best explanation I ever saw on this kind of problem, thank you very much!
Such a clear explanation - thank you so much!
thank you sir
Clear explanation!
Why is the normal force by surface only for m1 mass?
What is the slipping condition??
Very beautiful lecture. I wish our science department could provide the same level of quality.

Thanks a lot,our physics proffersor had given us hw to make the FBD for a similar diagram.this was really helpful for me

This seems a little advanced for 9th grade

Love you sir from india ❤️ 😍
At first I thought Dr. Peter Dourmashkin has the ability to write backwards
lol
We got johan cruyff back from the dead explaining physics
Why does N2,1 point downward? Shouldn't it point up?
No. That is the force exerted by block 2 on block 1.
Good how can I find all u r lectures sir
Because I am from diff country
This is MIT 8.01 classical mechanics. You can find all lecture on MIT website as mentioned in video description!
is he writing backwards? - physics student from tulane

that is not the matter but the issues is only concept
I thoght so first, but the video is probably flipped. That's why he's using his left hand to write (90% of people use their right hand)
@@TheRooster1337 are your RUclips channel exists now adays ?
How do u write opposite dirctionly?
How it is done: lightboard.info.
Thanks sir ,I understand concept clearly.-a student from India 7thgrade

wouldn't it be (m1+m2)g for Ng,1?
Yeah, I think so
No, wait acc no because N2=m2g and the forces going downstairs are n2+m2g, which is equal to m2g+m1g, which is equal (m1+m2)g
At last just equate the accelerations of two blocks
Didn't understand
