which has more mechanical energy, a box on the top shelf of a closet or a box of equal mass on the floor?\nthe box on the floor has more mechanical energy because work has been done on it.\nthe box on the shelf has more mechanical energy because it is higher above earths surface.\nthey have the same mechanical energy.\nthere is not enough information to know.\ndone

Answer

Brief Explanations:

Mechanical energy is the sum of kinetic and potential energy. Assuming both boxes are at rest (kinetic energy = 0), the box on the shelf has greater gravitational - potential energy ($U = mgh$, where $h$ is greater for the box on the shelf). So it has more mechanical energy.

Answer:

The box on the shelf has more mechanical energy because it is higher above Earth's surface.
