Why is gravitational potential energy always negative? |
| Answer» Gravitational potential energy is negative at the surface of Earth, because work is done by the gravitational field in bringing a mass from infinity.In other words, work has to be done on a body, if it is taken away from the gravitational field of the earth. Thus, potential energy is negative.For example, when a rocket is sent to space, work is done using fuels. | |
