By the end of this chapter you should be able to

 describe momentum and impulse and solve problems using them;

 apply impulse to realworld problems, including situations involving cushioning and impacts;

 define momentum conservation and describe applications of it;

 use momentum conservation to solve noncollision problems;

 distinguish among elastic, inelastic, and perfectly inelastic collisions;

 apply momentum conservation to solve collision problems; and

 determine whether a collision is elastic using energy arguments.
