Explanation of Solution
Introduction:
Angular momentum is the rotational equivalent of a linear momentum. It is a conserved quantity that means, for a closed system the total momentum remains conserved. It is the product of moment of inertia and angular speed and measured in radians per seconds. Torque is defined as the rate of change of angular momentum. In other words, torque is directly related to moment of inertia.
A child is on a circular motion ride. The angular momentum of the rod can be changed by applying external torque. A child can apply force along the handles of the circular track. Also momentum can be increased by running on ride and jump onboard.
