The '''moment of inertia''' is a measure of a mass and its distance perpendicular to an axis of rotation.
The '''moment of [[inertia]]''' is a measure of a [[mass]] and its distance [[perpendicular]] to an [[axis]] of rotation.
Mathematically, the moment of inertia ''I'' for a mass ''m'' that is moving a perpendicular distance of ''r'' from an axis is expressed as:
