Inelastic Collision

Collisions among objects are governed through laws of momentum and energy. While a collision occurs within an isolated system, the total momentum of the system of objects is conserved. Provided in which there no net external forces are acting upon the objects, the momentum of all objects before the collision equals the momentum of all objects after the collision. If there are only two objects included within the collision, then the momentum lost through one object equals the momentum obtained through the other object.
