Angular Work and Power

A torque which rotates an object must do work against friction.

Illustrative background for WorkIllustrative background for Work ?? "content


  • As an object rotates work is done to overcome the resistive frictional forces acting on it.
  • The equation for work done is:
    • Work = torque x angle turned through
    • W=TθW=T\theta
Illustrative background for Power Illustrative background for Power  ?? "content


  • As work is done to turn an object power is dissipated in the form of heat or sound energy.
  • The equation for power is:
    • Power = torque x angular velocity
    • P=TωP=T\omega
