Moment of inertia
- Moment of inertia of a body about a given axis is the sum of the products of masses of all the particles of the body and squares of their respective perpendicular distance from the axis of rotation.
- K.E. of rotation of body
- Mass (m) of the body is an analogue of moment of inertia (I) of the body in rotational motion.
