Question

what is the work done when a body is moved horizontally along frictionless surface ????? plz help !!!!!!!!!!

Answer 1

Heya buddy !
Here's yout answer :-

Since the surface is frictionless, there's no work done against friction force. Since the motion (and hence the surface) is horizontal, there's no change in potential energy.

Hope this'll help uh (:
