Angular Momentum: Angular momentum is the measure of an object's tendency to keep rotating at a constant speed around an axis. It depends on both the mass and distribution of mass of the object.
Conservation of Angular Momentum:Conservation of angular momentum states that if no external torque acts on a system, then the total angular momentum of that system remains constant.
Torque:Torque is the measure of how effectively a force can cause an object to rotate. It depends on both the magnitude and direction of the applied force as well as the distance from the axis of rotation.
