Question

Define law of momentum

Answer 1

The conservation of momentum can be derived from Newton’s second law of motion.



Thus the momentum of a particle or a system of particle doesn’t change if there is no external force acting on it. This is the law of conservation of momentum.

Hope this helps,

Answer 2

the conservation of momentum defined in the newton's second law of motion. the momentum or a particle of a system of a particle didn't change if there is no external force acting on it. this is known as law of conservation of momentum
