Question

state law of conservation of linear momentum of and prove the principal of conservation of momentum from newtons second law​

Answer 1

Answer: Law of conservation of linear momentum states that total momentum of the system is always conserved if no external force acts on an object or system of objects. Consider a collision between two balls wherein there occurs no energy losses during the collision.

Answer 2

Newton's third law states that for a force applied by an object A on object B, object B exerts back an equal force in magnitude, but opposite in direction. This idea was used by Newton to derive the law of conservation of momentum. ... B=m_{2}(v_{2}-u_{2}) (change in momentum of particle B)
