Answer:

Conservation of momentum is a fundamental law of physics which states that the momentum 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).

An example of law of conservation of momentum is Newton's cradle, a device where, when one ball is lifted and then let go, the ball on the other end of a row of balls will push upward.

Explanation:

The total momentum of an isolated system of interacting particles is constant. OR if there is no external force acting on the system, the total momentum remains conserved.Formula is

[m1u1+m2u2=m1v1+m2v2]

that is total momentum before collision=total momentum after collision.

example for bullet fired from a gun......here the LHS side of formula is 0 as initially the whole system is in rest...

therefore m1v1+m2v2=0.... you can apply this formula for any type of collision question.
