Question

Give scientific reason

The work done by an object moving in circular direction is zero.

ello:-​

Answer 1

Answer:

Force in uniform circular motion is always perpendicular to the displacement and hence the angle between F and S is 900 always. After putting the value of θ. W=0. Hence, The work done in a uniform circular motion is always zero

Answer 2

Explanation:

Work done on an object is the force applied and the displacement covered in the direction of the force applied. W=FScosθ. Force in uniform circular motion is always perpendicular to the displacement and hence the angle between F and S is 900 always. ... Hence, The work done in a uniform circular motion is always zero...
