Potential Energy



Potential energy is an energy that is stored due the positions of the bodies inside a force field
 There are several forms of potential energy.
Gravitational Energy is an energy stored because the height of objects. The higher it is an object and the heavier, the more gravitational energy is stored.
If a stone fells down a slope, it will lose potential energy and transform it in kinetic one.
Hydropower is another example of gravitational energy.
Mechanical Energy is energy stored in objects by tension. Compressed springs and stretched rubber bands are examples of stored mechanical energy
A tensed bow stores potential energy
Electrical Energy is what is stored in a battery, and can be used to power a cell phone or start a car. Electrical energy is delivered by tiny charged particles called electrons, typically moving through a wire. Lightning is an example of electrical energy in nature, so powerful that it is not confined to a wire.
Chemical Energy is energy stored in the bonds of atoms and molecules. Biomass, petroleum, natural gas, and coal are examples of stored chemical energy. Chemical energy is converted to thermal energy when we burn wood, coal to have a fire or burn gasoline in a car's engine.
Nuclear Energy is energy stored in the nucleus of an atom that is the energy that holds the nucleus together. Very large amounts of energy can be released when the nuclei are combined or split apart. Nuclear power plants split the nuclei of uranium atoms in a process called fission. The sun combines the nuclei of hydrogen atoms in a process called fusion
