Question

What is the work done on a body moving in a circular path

Answer 1

work done is zero bcoz
WORK DONE = FORCE × DISPLACEMENT
☆ but displacement in circular path is zero bcoz the initial and the final position is same
☆☆☆☆ WORK DONE = FORCE×0
SO, WORK DONE=0
hope it helps u

Answer 2

• The work done on a body moving in a circular path is zero. The reason for this is, when a body moves in a circular path, the centripetal force acts along the radius of the circle, which is at right angles to the motion of the body.

           As we know, Work done (W) = Force(F) . Dis[placement (ds)

                                                            = Fds×cos∅

           As ∅ = 90°

              Work done (W) = F.ds cos90 = 0

• Another way of understanding why the work done by a body moving in a circular path is zero is because the displacement of the body is zero.

       We know, Work Done (W) = Force × Displacement

                                                   = Force × 0

                                                   = 0

    Hence the work done on a body moving in a circular path is zero.
