Car and Truck in Head on Collision
Inelastic Collision : Collisions among objects are governed through laws of energy and momentum. Although a collision occurs inside an isolated system, the total momentum of the system of objects is conserved. Given that there are no net external forces 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 in the collision, after that the momentum change of the individual objects is equal within magnitude and opposite in direction.
