# Angular Acceleration

## Description

Torque, moment, or moment of force is the tendency of a force to rotate an object about an axis, fulcrum, or pivot.

Moment of inertia is the mass property of a rigid body that determines the torque needed for a desired angular acceleration about an axis of rotation.

Angular acceleration is the rate of change of angular velocity over time.

For all constant values of the torque of an object, the angular acceleration will also be constant. The constant angular acceleration can be calculated by the ratio of the total the torque of the object to the its moment of inertia.

## Variables

a | Angular Acceleration (1/s^{2}) |

T | Total torque (N*m) |

I | Moment of inertia ( angular momentum,/ angular velocity ) (kg*m^{2}) |
