Welcome to our Physics lesson on Work in Rotational Motion, this is the sixth lesson of our suite of physics lessons covering the topic of Dynamics of Rotational Motion, you can find links to the other lessons within this tutorial and access additional physics learning resources below this lesson.
In linear motion, Work if the dot product of Force applied on an object and the linear distance the object moves (see the Physics tutorial "Work. Energy. Types of Energy." Similarly, in the rotational world, work is done by a torque τ applied through some angle φ. Mathematically, we have
We use torque here instead of moment of force, as the process is dynamic, i.e. there is no work if the object doesn't move.
