Gravitational energy is the potential energy held by an object because of its high position compared to a lower position For example, a pen being held above a table has a higher gravitational potential than a pen sitting on the tableGravitational potential energy is mechanical energy minus kinetic energyFeb 09, 17 · Objects possess gravitational potential energy due to their position in a gravitational field The most common use of gravitational potential energy is for an object near the surface of the Earth, where the gravitational acceleration can be assumed to be constant at approximately 98 m/s 2 The zero of gravitational potential energy may be chosenMar 31, 16 · Potential energy is stored energy that can be converted into kinetic energy There are several forms of potential energy including gravitational, magnetic, electrical, chemical, and elastic potential energy The potential energy can become stronger or weaker based on circumstances affiliated with the form or potential energy
