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