# Moment of inertia

KidzSearch Safe Wikipedia for Kids.

**Moment of inertia** ([math]I[/math]), also called "**angular mass**" (kg·m^{2}),^{[1]} is the inertia of a rotating body with respect to its rotation.

It is a rotating body's resistance to angular acceleration or deceleration, equal to the product of the mass and the square of its perpendicular distance from the axis of rotation.

"The student is advised to regard moment of inertia as being equivalent to 'angular mass'; equations in rotational mechanics are generally analogous to those in translational mechanics. Wherever an equation occurs in translational mechanics involving mass*m*, there is an equivalent equation in rotational mechanics involving moment of inertia*J*. The units of moment of inertia are kilogram metres^{2}(abbreviation kg m^{2}).".
