jackson97: In circular motions, or more precisely uniform circular motion, resultant force which is known as centripetal force is directed towards center while the object moves at right angle to it at any instant. Mathematically, θ will become 90 degrees and cos(θ) is zero. Hence, the work done will be zero. Physically, there is no component of force in the direction of motion. Only one component remains which does not do work at all. Hence, the work done in a uniform circular motion is always zero.
