Define moment of inertia in terms of kinetic energy of rotation.

1.	Define moment of inertia in terms of kinetic energy of rotation.
Answer» " The moment of inertia of a rigid-body about an axis of rotation is numerically equal to twice the kinetic energy of rotation of the body, when rotating with unit angular velocity about that axis. I = 2(K.E.) or, K.E. = 1/2 lω².

" The moment of inertia of a rigid-body about an axis of rotation is numerically equal to twice the kinetic energy of rotation of the body, when rotating with unit angular velocity about that axis.

I = 2(K.E.)

or, K.E. = 1/2 lω².
