Angular acceleration

From Wikipedia, the free encyclopedia

Angular acceleration is the rate of change of angular velocity over time. In SI units, it is measured in radians per second squared (rad/s2), and usually denotes by the Greek letter alpha ({\alpha}\,). For constant values of angular acceleration, a rotating body conforms to the rotational equations of motion, in particular:

{\alpha} = \frac{\tau} {I} \,,

where

τ is torque
I is moment of inertia.
