Question

two balls each with with a mass of 0.5 kg, collide on a pool table. is the law of conservation of momentum satisfied in this collision

Answer 1

Sample Response: Yes, the law of conservation of momentum is satisfied. The total momentum before the collision is 1.5 kg • m/s and the total momentum after the collision is 1.5 kg • m/s. The momentum before and after the collision is the same.

Answer 2

Answer: yes, the law of conservation of momentum remains conserved always in a closed system.

Explanation:

Law of conservation of momentum states that initial momentum of the components in a closed system is equal to final momentum of the components. Thus, the total momentum remains constant i.e. conserved. The law of conservation of momentum hold true in all conditions - be it elastic collision or inelastic collision.

When two balls collide on pool table, the law of conservation of momentum is satisfied.
