Question

State the law of conservation of momentum.And also derive the equation for it.

Answer 1

Conservation of momentum is a fundamental law of physics which states that themomentum of a system is constant if there are no external forces acting on the system. It is embodied in Newton's first law (the law of inertia).The law of momentum conservation can be stated as follows. For a collision occurring between object 1 and object 2 in an isolated system, the totalmomentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.
