ACCELERATED MOTION - ROTATIONAL

Rotational acceleration occurs whenever a body changes rotational speed (RPMs) or direction (spin axis orientation). A body will gain or lose a constant amount of spin in a constant amount of time if the object is under a constant rotational acceleration.

rot. vel. gained (lost) = rot. accel. x time

Rotational accelerations are due to torques. The magnitude of the acceleration depends directly on the torque and inversely on the rotational inertia of the object under acceleration (bigger rot. inertia = smaller acceleration). Rotational inertia depends on the placement of the mass.

Rot. acceleration = Torque/Rot. Inertia
