Question

4. Define the moment of inerstia of a body give its units
and dimensions, what is the physical significance of
moment of
Inertia.​

Answer 1

Answer:

Moment of inertia is the inertia of rotation of an object.

It can be defined by applying the same logic.

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.metre
