What does the principle of conservation of momentum state?
- AA force is equal to the rate of change of momentum of the body upon which it acts.
- BIn a perfectly elastic collision, the relative momentum of the bodies before impact is equal to their relative momentum after impact.
- CThe momentum of a body is the product of the mass of the body and its velocity.
- DThe total momentum of a system of interacting bodies remains constant, providing no resultant external force acts on the system.
