Question

Why centripetal force does no work?

Answer 1

Answer:

The centripetal force is always perpendicular to the direction of motion. Only the component of the force in the direction of motion can do work. The centripetal force has no such component, so it can never do work.

Answer 2

Answer:

Explanation:

When an object is moving along the circular path then direction of its velocity is always in tangential direction and direction of centripetal force is always towards the centre (i.e. radial direction). we know that for a circle, its tangent is always perpendicular to its radius. So, In case of an object moving along the circular path, direction of centripetal force and direction of its motion both are perpendicular to each other. It means the angle between the direction of force and the direction of displacement is 90 degree.

So, W = F s cos90  and cos90 = 0

so, work done = W = F X S X 0 = 0
