State the Law of Conservation of Angular Momentum. The Law of Conservation of Angular Momentum states that angular momentum remains constant if the net external torque applied on a system is zero. So, when net external torque is zero on a body, then the net change in the angular momentum of the body is zero. Derive the expression for the Law of Conservation of Angular Momentum Momentum, product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction.
