Difference between gravitational potential energy and gravitational potential. |
| Answer» Gravitational potential energy is energy an object possesses because of its position in agravitational field. The most common use ofgravitational potential energy is for an object near the surface of the Earth where thegravitational acceleration can be assumed to be constant at about 9.8 m/s2.The gravitational potential (V) is thegravitational potential energy (U) per unit mass: where m is the mass of the object.Potential energy is equal (in magnitude, but negative) to the work done by thegravitational field moving a body to its given position in space from infinity. | |
