Which energy is related to an object's height in the gravitational field?

Gravitational potential energy is specifically defined as the energy an object possesses due to its height in a gravitational field. This form of energy increases as an object's height above the ground increases. The gravitational potential energy is dependent on both the height of the object and the mass of the object, as well as the acceleration due to gravity.

When an object is lifted to a higher position, work is done against the gravitational force, which results in an increase in gravitational potential energy. This energy has the potential to be converted into kinetic energy if the object falls.

In contrast, elastic potential energy relates to deformed objects like springs, electrical energy refers to energy from electric charges, and mechanical energy encompasses both kinetic and potential energy but does not specify the source of potential energy. Therefore, gravitational potential energy is the correct answer when discussing energy related specifically to an object's height in a gravitational field.
