Gravitational energy or gravitational potential energy is the potential energy a massive object has due to its position in a gravitational field. It is the mechanical work done by the gravitational force to bring the mass from a chosen reference point (often an "infinite distance" from the mass generating the field) to some other point in the ...

22 gru 2020 · Gravitational potential energy (GPE) is an important physical concept that describes the energy something possesses due to its position in a gravitational field. The GPE formula GPE = mgh shows that it depends on the mass of the object, the acceleration due to gravity and the height of the object.
The change in gravitational potential energy \(\Delta PE_g\), is \(\Delta PE_g = mgh\), with \(h\) being the increase in height and \(g\) the acceleration due to gravity. The gravitational potential energy of an object near Earth’s surface is due to its position in the mass-Earth system.
Newton's law of universal gravitation can be used to derive an equation for gravitational potential energy that is useful for astronomical problems.
Gravitational potential energy is energy an object possesses because of its position in a gravitational field. The most common use of gravitational potential energy is for an object near the surface of the Earth where the gravitational acceleration can be assumed to be constant at about 9.8 m/s 2 .
Potential energy is particularly useful for forces that change with position, as the gravitational force does over large distances. In Potential Energy and Conservation of Energy, we showed that the change in gravitational potential energy near Earth’s surface is \[ \Delta U = mg(y_2− y_1) \label{simple}\]
