# Moment of inertia

## Explanation[edit]

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 = mr ^{2}**. The unit of moment of inertia is

**kg m**.
