CHAPTER OBJECTIVES 7:  Momentum
•Distinguish by definition between elastic, inelastic and completely inelastic
collisions. 
•Relate energy changes in elastic and completely inelastic collisions. 
•Understand that momentum and kinetic energy are conserved in elastic        
 collisions. 
•Apply the Law of Conservation of Linear Momentum to problems involving
 colliding bodies. 
•Use energy and momentum principles to discuss what occurs after an elastic
 collision has stopped. 
•Predict the velocities of two colliding bodies after impact when the masses 
 and initial velocities are given. 
•Apply the Law of Conservation to solve recoil problems. 
•Predict the scattering angles after a two-dimensional elastic collision.
