Question

Define and explain the conservation of momentum.?

Answer 1

The law of conservation of linear momentum is a fundamental law of nature, and it states that the total momentum of a closed system of objects (which has no interactions with external agents) is constant. One of the consequences of this is that the center of mass of any system of objects will always continue with the same velocity unless acted on by a force from outside the system.

sum of the momenta before the collision must equal the sum of the momenta after the collision:
