1. 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.

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

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

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

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