work-energy in rotation

Question

Net torque does work equal to change in:

RankGuru · Accepted Answer

The Work-Energy Theorem for Rotation states that the work done by a net torque on a rigid body is equal to the change in its rotational kinetic energy:
$W = \int 	au d	heta = \Delta K_{rot} = \frac{1}{2} I \omega_f^2 - \frac{1}{2} I \omega_i^2$
This is the rotational equivalent of $W = F d = \Delta K_{trans}$.
