College Physics 1: Lecture 27 - Conservation of Momentum

In this lecture, we introduce an important law of physics - conservation of momentum. This is the first conservation law we deal with, and many problems can be solved via it's application.

if you have a lecture on angular momentum can you please post it? it would be greatly appreciated.

41:40, why does it have the largest momentum? Pf-pi =0 (since it's bouncing back), while our clay ball has pf of 0 which means ∆p=p and fully acted the force on the door?? Plus ain't it external force? Shouldn't it be equal... I'm really confused 😕
