When two bodies interact, the forces they exert on each other are equal and opposite. The resultant force acting on a body is equal to the rate of change of its momentum. momentum and total energy are conserved. An object will remain at rest or keep travelling at constant velocity unless it is acted on by a resultant force. It is transferred into other forms of energy (such as heat or sound). Most collisions are inelastic.
