we differentiate between elastic and inelastic collisions. The conservation of momentum and the conservation of energy are explored as we do examples involving these two types of collisions.

Elastic and inelastic collisions are described. Students learn to state the law of conservation of momentum and define a closed, isolated system.

This is the law of conservation of momentum. It is true for all collisions. Watch this video for a practical demonstration of conservation of momentum in elastic collisions.
