2020年12月22日 · 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 is usually given the symbol U g . It represents the potential an object has to do work as a result of being located at a particular position in a gravitational field. Consider an object of mass m being lifted through a height h against the force of gravity as shown below.
- You are correct. Good catch. I have reported it to the person in charge of the physics section at KA.

2022年9月29日 · Gravitational potential energy is the energy possessed by an object due to its position in a gravitational field. When the object moves from one position to another, its gravitational potential energy change equals the work done in moving the object.
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 ...
2022年2月20日 · Potential energy is a property of a system rather than of a single object—due to its physical position. An object’s gravitational potential is due to its position relative to the surroundings within the Earth-object system. The force applied to the object is an external force, from outside the system.
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
Newton's law of universal gravitation can be used to derive an equation for gravitational potential energy that is useful for astronomical problems.
