Torque Torque (t) – measure of the ability of a force to rotate an object around an axis (fulcrum). Torque is not a force. It is a rotational analog to force.

Torque Point mass - considers only a single point rotating about an axis Extended object (mass) – considers whole object rotating about an axis

Torque Rotational motion – motion around an axis of rotation Translational motion – linear motion

Torque Torque = force x radius t = F x r units: N m (tau)

Torque Force at an angle = Fsinq x r = F x r sinq
