Answer 1

Answer:

Moment of inertia is defined as the tendency of an object to remain in a state of rest or of a constant rotational velocity. Greater the moment of inertia, more torque is required to change this state. Torque in rotational motion plays the same role as force in linear motion. Its SI unit is kg. metre2.

Answer 2

Answer:

Inertia is the property of a body due to which it resists a change in the state of rest or of motion.

The SI unit of inertia is kilogram metre per square.
