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