The law of conservation of momentum states that the total momentum of interacting objects does not change.
This means the total momentum before a collision or explosion is equal to the total momentum after a collision or explosion.
Explanation:
The law of conservation of momentum is derived from Newton's third law of motion which states that action and reaction are equal and opposite.
The law of conservation of momentum can be stated as follows.
For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.
