When two objects collide, their motions are changed as a result of the collision, as is shown when playing pool. There are several laws governing collisions, the principal one being the law of conservation of linear momentum, which says the total momentum of an isolated system is the table and the balls, and the law then implies that the tota ...

... answer however, we must find out what type of collision takes place, whether it is elastic or not elastic. The type of collision is characterized by what is called the coefficient of restitution. This quantity is approximately constant for a collision between two given objects, and can be determined experimentally. If the relative velocities of the two objects are the same before and after impact, the coefficient is equal to 1, and the collision is elastic. In practice, however, such perfectl ...
