1. Gravitational energy is potential energy stored in an object based on its distance from the Earth. Potential energy is energy that is stored in an object or substance. Gravitational energy is a form of potential energy. The Earth, the Sun, planets and stars all produce significant amounts of gravity
2. The condensation of matter releases gravitational energy which is transformed into kinetic energy of the particles in the gas cloud, increasing temperature and pressure. As the density increases, radiation transport through the cloud becomes more difficult, leading to more rapid heating of the gas
3. All conservative forces have potential energy associated with them. The force of gravity is no exception. Gravitational potential energy is usually given the symbol . It represents the potential an object has to do work as a result of being located at a particular position in a gravitational field
4. Gravitational energy is the movement of an object or mass that is caused by the pull of gravity. This is caused on Earth by the strong attraction of all other masses to be drawn back to Earth's center
5. Gravitational energy is the largest component of the budget (Table 2) and special care is warranted to evaluate how it gets converted to other forms of energy when the planet contracts. This has been discussed in a series of papers ( Lapwood, 1952; Flasar and Birch, 1973 )
6. In classical mechanics, the gravitational potential energy (U) is energy an object possesses because of its position in a gravitational field. Gravitational potential (V; the gravitational energy per unit mass) at a location is equal to the work (energy transferred) per unit mass that would be needed to move the object from a fixed reference location to the location of the object
7. Gravitational energy is the potential energy associated with gravitational force, as work is required to elevate objects against Earth's gravity. The potential energy due to elevated positions is called gravitational potential energy, and is evidenced by water in an elevated reservoir or kept behind a dam
