Today we will introduce momentum and impulse. We will learn that momentum p = mv and that the change in momentum = impulse FΔt. We will look at examples of how impulse is altered. We will also discuss conservation of momentum in a collision.

We'll do test corrections during one of these periods as well.

#### Conservation of momentum (Challenger Center)

In the following video, the chart is a useful method, but if you'd rather express the conservation of momentum as an equation like we did conservation of energy, that would be acceptable and probably faster.  We'll see examples in class.  Focus on understanding the concepts of momentum conservation here. Don't forget to take notes.

#### Conservation of Momentum (Dan Fullerton)

Below is an example of how to solve a perfectly inelastic collision the equation way, which is preferred over the chart method.
