Question

Give Reason
Work done by an object performing uniform circular motion is zero.​

Answer 1

Answer:

here it is your answers thank me.

Explanation:

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.

Answer 2

Answer:

w=f×d but in circular motion there is only centripetal force ,hence displacement and force are in opposite directions w=0
