# Torque?

Practice exercises from today: Worksheet 1 # 1-4, 6, 7

Torque is the rotational equivalent of force – just like angle (degrees, radians) is the equivalent of distance. To calculate torque we must first identify the axis of rotation – the “center” that the torque is causing a rotation around. We identify where the force is being applied and multiply the distance from the axis it is being applied at (the radius) by the perpendicular component of the force.

Note the intuitive aspect of this: the farther from the axis you apply a force, the more torque (think “leverage”) you create.
