Question

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

Answer 1

Answer:

beacause the displacement is zero

and the formula for work is

w=Fd

if displacement is zero then the work is also zero

Answer 2

Answer:

W=FScos.Force is uniform circular motion is always perpendicular to the displacement and hence the angle between F and S is 900 always. W=0.Hence, the work done in a uniform circular motion is always zero
