Question

when a body perform uniform ciecular motion the work done is zero
​

Answer 1

Answer:

For an object moving in uniform circular motion, the only force is the centripetal force, which points in a direction along the radius of the circle, and since the radius of the circle never changes, there is no displacement along this direction, and the work done by this force is zero.

Answer 2

Explanation:

work done on an object is product of force applied and the displacement covered in the indirect of force applied ........ Hence , the work done in a uniform circular motion is always zero .

I think this is a right answer
