Chapter : Moment of Inertia : Physical Significance of Moment of Inertia : The kinetic energy of rotation of a body which rotates with an angular velocity ω is E kr = (1/2) I ω ^ 2 ; Where I is the moment of inertia ...
The kinetic energy of translational of the body which moves with a linear velocity v is E kt = (1/2) m v ^ 2 ....
If E kr & E kt are compared , it can be concluded that the mass is an analogue to the moment of inertia in rotational motion ... The moment of inertia plays the same role in rotational motion as mass plays in linear motion...
