Question based on moment of inertia

Dimensions of moment of inertia are

The rotational kinetic energy of two bodies of moment of inertia 9 kg m^(2) and 1kg m^(2) are same . The ratio of their angular momenta is

The rotational kinetic energy of a rigid body of moment of inertia 5 kg-m^(2) is 10 joules. The angular momentum about the axis of rotation would be -

Obtain an expression for kinetic energy of rotation of a body. Hence define moment of inertia of the body. Explain its physical significance.

In rotatory motion, moment of inertia
