Assume that a friend hands you a heavy book to hold as he turns the combination lock on his locker. Which of you does more work?

Respuesta :

None of you do work because work also requires movement from one place to another.

Answer:

None of us is doing work

Explanation:

None of us is undergoing work because it is said that for work to be done a force applied to a body must cause the body to move through a "distance". According to both me and my friend, we are both at a particular position (not covering any distance) and as such work has not been done by any of us not until we leave our position of rest to cover a particular distance.
