Energy Stores

There are several different stores of energy. They are:

 

  • Magnetic energy 

  • Kinetic energy

  • Gravitational potential energy 

  • Elastic potential energy 

  • Electrical energy 

  • Chemical energy 

  • Nuclear energy 

  • Thermal/internal energy

 

A Magnetic store - energy is stored when two magnets (objects) are attracting or repelling each-other, for as long as their magnetic poles remain apart. This can also be a magnet and a magnetic material such as a piece of steel.

 

Kinetic energy store - energy stored in a moving object.

 

Gravitational potential energy store - energy stored in an object that is raised up against the pull of gravity.

 

Elastic potential energy store - energy is stored in a stretched elastic band, spring, etc. 

 

Electrical energy store - Some objects carry electrical charges and create electric fields. These charged objects can exert forces on each other. 

 

Chemical energy store - energy is stored in the bonds in chemical elements such as batteries, food or fuel, etc.

 

Nuclear energy store - energy is stored in the nuclei of an atom and is released during nuclear fission or nuclear fusion or radioactive decay.

 

Thermal/internal energy store - energy stored in an object with heat (all objects).
