Question

Calculate the amount of work done under centripetal force. Give reason of your answer.​

Answer 1

$\huge\star{\green{\underline{\mathfrak{Answer:-}}}}$

This would mean that the force is always directed perpendicular to the direction that the object is being displaced. The angle Theta in the above equation is 90 degrees and the cosine of 90 degrees is 0. Thus, the work done by the centripetal force in the case of uniform circular motion is 0 Joules.

This would mean that the force is always directed perpendicular to the direction that the object is being displaced. The angle Theta in the above equation is 90 degrees and the cosine of 90 degrees is 0.

Thus, the work done by the centripetal force in the case of uniform circular motion is 0 Joules.
