Dive into Unit 6 of AP Physics 1: Energy and Momentum of Rotating Systems! This video covers rotational kinetic energy, torque, work, angular momentum, rolling without slipping, and conservation laws. Watch as we connect linear and...

A racquetball is dropped on to three different substances from the same height above each: water, soil, and wood. Rank the _______ during the collision with each substance in order from least to most. (a) Impulse. (b) Average Force of...

By the time students learn about all the equations for mechanical energy, momentum, impulse and impact force, they often start to confuse the equations with one another. This is a straightforward, simple look at all of those equations...

Demonstrating and measuring how a helmet changes impulse, impact force and change in time during a collision.

Wearing a helmet is all about impulse, change in momentum and the force of impact. This video illustrates why you should secure your helmet to your head. Thank you very much to Colton and Jean Johnson who said yes when I asked them if...

This video is a lecture presentation on the topic of momentum and safety. The presenter discusses the relationship between force and rate of change of momentum and provides examples of how changing the force acting on an object during a...

Well, the moment has finally arrived and in this episode, we will try to answer this burning question. But before we get into this entertaining experiment, first… Coyote will put himself into the position of a prey item by comparing the...

Calculus based review of conservation of momentum, the momentum version of Newton’s second law, the Impulse-Momentum Theorem, impulse approximation, impact force, elastic, inelastic and perfectly inelastic collisions, position, velocity...
