Question

When a body moves in a circular path how much work is done for three half rotation?

Answer 1

Answer:

Hey!

The work done by a force in moving a body is W= F . s

where

s

is the displacement vector.

In a circular path, the force is centripetal, thus always acting towards the center along the radial direction.

However the displacement is always along tangent to the circle at the instantaneous position of object.

Thus W= F . s =0
