Collisions

A collision is when two or more objects colide with each other while either in movment or while sitting still.
 * Collisions **

There are three main types of collisions in physics 1) Totally elastic 2) Less elastic 3) Totally inelastic


 * **Elastic** || **Less elastic** || **Inelastic** ||
 * No kinetic energy is lost. Since KE is not lost, no energy can go into heat or sound || Less damage or heat created || The colliding objects stick together and become one. ||
 * Usually involves only collisions where the objects can't touch || Less sound created || Involves the greatest loss of Kinetic Energy. ||
 * No damage caused to either colliding object ||  || The colliding objects usually suffer some kind of permanent damage ||
