Gravitational Potential Energy is the energy an object possesses due to its position in a gravitational field. It is calculated using the formula: GPE = mass × gravity × height. The higher an object is above the ground, the more gravitational potential energy it has. For example, a book on a shelf has more gravitational potential energy than one on the floor. This type of energy is important in various fields, including physics and engineering. When an object falls, its gravitational potential energy converts into kinetic energy, which is the energy of motion. Understanding gravitational potential energy helps explain how objects move and interact under the influence of gravity.
