3.3 Linear momentum and its conservation

1 state the principle of conservation of momentum
2 apply the principle of conservation of momentum to solve simple problems, including elastic and
inelastic interactions between objects in both one and two dimensions (knowledge of the concept of
coefficient of restitution is not required)
3 recall that, for a perfectly elastic collision, the relative speed of approach is equal to the relative speed of
separation
4 understand that, while momentum of a system is always conserved in interactions between objects,
some change in kinetic energy may take place
