Work Done in Uniform Circular Motion

When a body moves with a constant speed along a circle:

(1994)

No work is done on it
No acceleration is produced in it
Its velocity remains constant
No force acts on it

Solution:

In uniform circular motion, the centripetal force is always perpendicular to the instantaneous displacement. Work \(W = F.d cos\theta\). Since \(\theta = 90^{\circ}\), \(cos\theta = 0\). Therefore, \(W = 0\).
