Momentum and Collisions
... This theorem states that an external force applied over a certain time interval will change an object’s momentum. A small force applied over a long time will have the same effect in momentum as a large force applied over a short time assuming constant forces. F∆t = ∆p is the impulse – momentum theor ...

... I’m going to try something that I think will help you guys learn: since we’ve already covered conservation of energy, I want you you to try to puzzle through the application of this concept to rotational motion yourself, to help you build intuition for these equations and how to use them. To do that ...

... This equation is satisfied if P = k N. However, we know from experience that friction generates heat, a form of energy that does not seem to be accounted for in this equation. It can be shown that the work term (k N)s represents both the external work of the friction force and the internal work th ...
