Question

Why is the work done on an object moving with uniform circular
motion, zero?
​

Answer 1

Answer:

Work done is equal to Force (acting in the direction of displacement) times the displacement i.e. W=F.S where (.) is dot product. ... Scos(θ), since body is moving in circular track cos(θ)=0 , and hence whole term will be 0 i.e. Work done will be 0.
