Moment of Inertia in rotational motion is same as the mass in linear motion. Moment of inertia of a body is its property which keeps it in its own position of rest or in uniform circular motion in rotational dynamics. It tries to maintain the original state of the body unless an external torque is applied. showbox for ios

"The moment of inertia about an axis of a body is calculated by summing for every particle in the body, where is the perpendicular distance to the specified axis. To see how moment of inertia arises in the study of the movement of an extended body, it is convenient to consider a rigid assembly of point masses.
