Moment of inertia

Explanation

Moment of inertia is the rotating body's resistance to the angular acceleration and deceleration. It is also called as rotational inertia and angular mass. Moment of inertia I for a point mass can be determined by the product of its mass m and the square of the distance r from the axis of interest. The equation is represented as I = mr². The unit of moment of inertia is kg m².
