Question

Which one of the following statements is true? (A) Momentum is conserved in elastic collisions but not in inelastic collisions (B) Total kinetic energy is conserved in elastic collisions but momentum is not conserved in elastic collisions (C) Total kinetic energy is not conserved but momentum is conserved in inelastic collisions (D) Kinetic energy and momentum both are conserved in all types of collisions

Tardigrade Admin · Accepted Answer

The law of conservation of momentum is true in all type of collisions, but kinetic energy is conserved only in elastic collision. The kinetic energy is not conserved in inelastic collision but the total energy is conserved in all type of collisions.
