In which situation is no work being done?

a person carrying a box from one place to another

a person picking up a box from the ground

a person pushing a box from one place to another

a person pulling a box from one place to another

Respuesta :

I would say that work is being done in all the situations because technically in physics work is done whenever force is applied through a distance.

A. because the box is being carried at a constant velocity, therefor there is no net force necessary to keep it it motion.  It changes the direction in motion, but it does no work on the box
