Question

f. Why is the work done on an object moving with upiform circular motion zero? Explain​

Answer 1

Explanation:

The work done on an object moving with uniform circular motion is zero because, the work done is a vector quantity in which displacement and direction are absolutely necessary. Since in circular motion, at every point of motion the direction always changes, therefore the work done is zero.

Note - There can be another point as- since after a complete motion or a complete circulation the displacement will be zero as the body will again come at the initial position that's why the work done is zero .
