A particle of mass $m$ is moving in a circular path of radius $r$ with a cons ant speed $v$. If the particle is subjected to a centripetal force $F_c = \frac{mv^2}{r}$, what is the work done by this force as the particle moves through an angle $ heta$?

A particle of mass $m$ is moving in a circular path of radius $r$ with a cons	ant speed $v$. If the particle is subjected to a centripetal force $F_c = \frac{mv^2}{r}$, what is the work done by this force as the particle moves through an angle $	heta$?

Accepted Answer

$ W = \frac{1}{2}mv^2\( 1 - \cos\theta \ $ )
