A 20 kg mass stores twice as much gravitational potential energy as a 10 kg mass at the same height. The higher up an object is, the more energy it stores. A mass 10 m above the ground stores twice as much energy as the same mass only 5 m above the ground. A stronger gravitational pull will also result in more gravitational potential energy.
Gravitational potential energy is the energy possessed by masses according to their spatial arrangement and the gravitational force (one of the four fundamental forces) that pulls them towards one another. [2] Since Earth is so large compared to the objects on it, it''s easy to watch these objects being pulled (falling) towards the center of the
Gravity energy storage systems depend on the principle of lifting one or more solid masses a vertical distance in order to increase their gravitational potential energy. The system must then be reversible to allow the lowering of the weight(s) to result in useful release of the stored energy, less any efficiency losses.

Gravity energy storage is a form of mechanical energy storage that uses the earth''s gravity to store energy. The energy is stored in the form of potential energy, which is the energy that an object possesses due to its position relative to other objects. The higher an object is placed, the greater its potential energy.
