Gravitational potential energy: energy due to the effects of gravity on an object (the higher the object is the more gravitational potential energy it has)
Nuclear energy: energy due to the re-arrangement of particles or the splitting of the atoms’ nucleus
Elastic energy: energy due to a material being stretched and then released
Chemical energy: energy due to chemical reactions between substances
Electric energy: energy due to electrons (tiny charged particles ,that come from atoms) that transfer energy for example a battery to a light bulb
