The general expression for gravitational potential energy arises from the law of gravity and is equal to the work done against gravity to bring a mass to a given point in space. Because of the inverse square nature of the gravity force, the force approaches zero for large distances, and it makes sense to choose the zero of gravitational potential energy at an. 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 Gravitational Potential Energy. In classical mechanics, the gravitational potential energy (U) is energy an object possesses because of its position in a gravitational field. Gravitational potential (V; the gravitational energy per unit mass) at a location is equal to the work (energy transferred) per unit mass that would be needed to move the object from a fixed reference location to the. Gravitational potential energy may be converted to other forms of energy, such as kinetic energy.

The full name of this effect is gravitational potential energy because it relates to the energy which is stored by an object as a result of its vertical position or height Gravitational potential energy is directly related to both mass and height. The greater the mass the greater will be the gravitational potential energy. Similar is the case with height, an object at a higher elevation will have greater gravitational energy stored in it Gravitational potential energy near Earth's surface may be computed by multiplying the weight of an object by its distance above the reference point. In bound systems, such as atoms, in which electrons are held by the electric force of attraction to nuclei, the zero reference for potential energy is a distance from the nucleus so great that the electric force is not detectable

The same arguments apply here to both potential energy and potential Gravitational potential energy is the energy possessed by masses according to their spatial arrangement and the gravitational force (one of the four fundamental forces) that pulls them towards one another. Since Earth is so large compared to the objects on it, it's easy to watch these objects being pulled (falling) towards the center of the planet, not the planet being pulled towards the object How gravitational potential energy changes to kinetic Various gravitational potential energy problems The reason we know gravitational potential energy exists Skills Practice Gravitational energy is potential energy stored in an object based on its distance from the Earth.
