Moment Of Inertia Of Rigid Body

If the moment of inertia of a body is I and its mass be M the, its radius of gyration would be

Define the moment of inertia of a ’rigid body and write its SI unit.

Define moment of inertia of a body capable of rotation about an axis. Show that the moment of inertia of a body an axis is numerically equal to twice its kinetic energy if it rotates with unit angular velocity.

Assertion : The moment of inertia of a rigid body reduces to its minimum value, when the axis of rotation passes through its centre of gravity. Reason : The weight of a rigid body always acts through its centre of gravity.
