You are absolutely amazing at explaining this stuff. Very organized videos and consistent with terms, so much better than any professor I have ever had or physics videos i have watched. You get straight to the point rather than confusing people with crazy explanations. Thank you so much!
On video (3 of 11) of Angular Momentum, you said the moment of inertia for the child on the disk is "MR^2" but on this video, you said "1/2MR^2", why is it multiplied by 1/2?
How to calculate final angular velocity if initial angular velocity of disc_1 is 0? So angular momentum of the disc_1 is 0 to, so disc_1 has no influence on final velocity? Thank you sir.
Even if disc 1 does not have any initial angular velocity, it will still affect the final velocity. (You still have to add its moment of inertia to the denominator, slowing down the final angular velocity.

Amazing Sir, Thank You. Helps a lot for Classical Mechanics at University. We'll all try our best to leave likes and subscribe! Thanks a lot sir!
Thnx a lot sir u made my basics strong
Glad to hear that

A child can be considered a "point mass" and thus has a moment of inertia = mR^2 A solid disk has a moment of inertia = (1/2) mR^2
@@MichelvanBiezen oh makes sense, thank you so much for all you do!! I can't thank you enough!!
Thank-you multiplied by limx->0 (1/x)

@@MichelvanBiezen oh yes, forgot the second part of equation. I really enjoy your lectures, thank you!
thank you bro 😻
Welcome 😊
5:58 "As a threesome". xD
is this necessary condition that all discs are a coaxial, please explain that professor
It makes the problem a lot easier but it is not required. You would have to use the parallel axis theorem for each disk if they were not coaxial.
no
