# Work done in non-uniform circular motion

In non-uniform circular motion, the work done by force should not be zero because tangential force acts on body. Is this correct? If I am wrong, please give a proper explanation.

Of course. . . Work done is stored in the body as its rotational kinetic energy i.e, $$\tau \theta = \Delta KE_{rot}$$ If torque is zero, then $\tau=0$ and thus there is no change in rotational kinetic energy. Then the motion is said to be uniform circular motion.
