Found in: Fuels, food, and batteries.
How it works: Released during chemical reactions, such as combustion or metabolism in living organisms.
Found in: Moving objects.
How it works: The energy possessed by an object due to its motion. The faster it moves, the more kinetic energy it has.
Found in: Objects held above the ground.
How it works: Energy stored in an object because of its position in a gravitational field. The higher the object, the more gravitational potential energy it has.
Found in: Stretched or compressed objects, like springs or rubber bands.
How it works: Energy stored when an object is deformed but can return to its original shape.
Found in: Any object; the hotter it is, the more thermal energy it stores.
How it works: This is the internal energy of an object due to the movement of its particles. Higher temperatures mean more energetic particles.
Found in: Magnets and objects that interact with them.
How it works: Energy due to magnetic fields and the positions of magnetic objects.
Found in: Charged objects.
How it works: Stored due to the positions of electrically charged objects relative to each other.
Found in: The nuclei of atoms.
How it works: Energy stored in the nucleus of an atom. It can be released in nuclear reactions, such as fusion or fission.
Each of these stores can be transferred from one to another, often through work done by forces or through heating.
