Correct Answer: angular velocity

Solution : The correct answer is angular velocity.

Inertia is a property of the body in which it resists any change in its state of motion. Moment of inertia is a physical property of matter in which it resists any change in its rotational motion. It is calculated using the mass of body and distribution of mass around the axis of rotation. The higher the moment of inertia of the body higher would be the energy required i.e. torque to change its angular velocity. In simpler terms it is used to describe how easily a body can rotate on its axis and its calculation is independent of angular velocity.
