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.

Kinetic energy can also be transferred from one body to another in a collision, which can be elastic or inelastic. One example of an elastic collision would be one billiard ball striking another.

This is shown in the diagram below. After the collision, the blue ball travels from left to right at 0.18 ms-1. a) Calculate the velocity of the red ball after the collision. b) Use kinetic energy ...
