What is the definition of GPE and how does it relate to the concept of potential energy?

Gravitational potential energy (GPE) is the energy stored in an object due to its position in a gravitational field. It is directly related to an object's height above a reference point and its mass. The higher an object is lifted, the greater its gravitational potential energy. When the object falls, this potential energy is converted into kinetic energy as it accelerates towards the ground.
