Work Done By a Constant Torque – Power & Moment of Inertia – Rotational Motion Physics Problems

This physics video tutorial explains how to calculate the amount of work done by a constant torque. It also explains how to calculate the rotational power of a rotating object using torque and angular velocity. Rotational work is equal to the product of the torque and angular displacement. Rotational work is also equal to the change in rotational kinetic energy which can be found using the moment of inertia of the object and its angular speed. This video contains plenty of examples and practice problems on rotational motion and energy.
