Question

What real-world examples show no work being done? Any resisting the force of gravity?

Answer 1

A waiter carrying plates at a constant height, holding up a large weight, and trying to push an elephant but it won't move.

Answer 2

Thanks !!

Answer 3

Picking up a box and putting it back down exactly where it was, so there is no displacement.

Answer 4

I interpreted the question as no work being done period rather than no NET work being done.
