Question

State the law of conservation of momentum and prove it based on Newton's second
law of motion.​

Answer 1

Explanation:

Derive law of conservation of momentum from Newton's second law of motion

Consider a force F acts on a body of mass m and changes its velocity from u to v in t seconds. According to Newton's second law, the rate of change of momentum is directly proportional to the applied force. The unit of force is so chosen that k is equal to one. If m = 1, a = 1 and F = 1, then k = 1.
