Describe the work done on a rigid system by a given torque or collection of torques.

A torque can transfer energy into or out of an object or rigid system if the torque is exerted over an angular displacement.

The amount of work done on a rigid system by a torque is related to the magnitude of that torque and the angular displacement through which the rigid system rotates during the interval in which that torque is exerted. Relevant equation:

Work done on a rigid system by a given torque can be found from the area under the curve of a graph of the torque as a function of angular position.
