What three factors decide how much gravitational potential energy a body has?

1. Mass

2. Height

3. Gravitational Force Field

Explanation:

The three factors that decide how much gravitational potential energy a body has are: 1) The mass of the body itself, 2) The relative height at which the body is, because gravitational force varies with height i. e distance away from earth surface. 3) and finally the strength of the gravitational field the body is in.
