It is defined as the ratio of the relative velocity of separation to the relative velocity of approach of the two objects just before and after the collision.<\/p>\n<p>For perfectly elastic bodies, the COR is 1. This means that no energy is lost during the collision, and the two objects rebound off of each other with the same speed that they had before the collision.<\/p>\n<p>For perfectly inelastic bodies, the COR is 0.
