Consider making an analogy between the gravitational potential energy associated with a mass being moved near the surface of the earth and the electric potential energy associated with a moveable charge. electric potential (not electric potential energy) is to charge as is to mass.

Gravitational potential

Explanation:

The gravitational potential at a point in the gravitational field is defined as the work per unit of mass that a force must carry out to transport a body, at a constant speed, from a fixed reference location to that point.

The negative sign indicates that the work done by the gravitational force implies a decrease in gravitational potential.
