What is Inertia?
Inertia is the property of a matter by virtue of which it tends to resist the change in the state of its motion. This means a body in rest tries to remain at rest and resist any force trying to bring it into motion, and a body in motion tries to continue in motion and resist any force trying to bring it to change the magnitude of its motion. In terms of quantity, it is equal to the maximum force trying to change its state of motion.

Moment of Inertia
Moment of inertia is the property of a body in rotational motion. Moment of Inertia is the property of the rotational bodies which tends to oppose the change in rotational motion of the body. It is similar to the inertia of any body in translational motion. Mathematically, the Moment of Inertia is given as the sum of the product of the mass of each particle and the square of the distance from the rotational axis. It is measured in the unit of kgm2.
