# Gravitational Potential Energy vs. Potential Energy: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Published on January 2, 2024
Gravitational potential energy is the energy an object possesses due to its position in a gravitational field. Potential energy is the stored energy in an object due to its position or state.

## Key Differences

Gravitational potential energy is a form of potential energy that depends on an object's height and mass within a gravitational field, such as Earth's gravity. Potential energy, more broadly, encompasses any stored energy in an object, which can include gravitational, chemical, elastic, and more.
The value of gravitational potential energy increases as an object is raised higher in a gravitational field, directly proportional to its height and mass. Potential energy, in general, can be stored in various forms, like in a compressed spring or a charged battery, not just due to height.
Gravitational potential energy is specifically relevant in scenarios involving gravitational forces, such as a rock held at a height. In contrast, potential energy is a wider concept used in different physics areas, like in chemical bonds or stretched materials.
Calculation of gravitational potential energy typically involves the object's mass, gravitational acceleration, and height from a reference point. Conversely, calculating potential energy can vary greatly depending on the energy form, like using spring constants for elastic potential energy.
In physics, gravitational potential energy is crucial for understanding phenomena like orbital mechanics or free-fall motion. Potential energy, as a broader term, is essential in fields ranging from mechanical engineering to chemistry, indicating energy that could be converted into kinetic energy or work.
