How to Practise Elastic and Inelastic Collisions
Start with conservation of momentum in one dimension and the final velocities in an elastic collision, then compare a perfectly inelastic collision where the bodies move together and kinetic energy is lost. The coefficient of restitution is 1 for an elastic collision and 0 for a perfectly inelastic one.
Finish with collisions in two dimensions and the questions on energy lost in a collision.
