Types of Potential Energy

Chemical – energy stored in bonds of atomsEx. Biomass, coal, petroleum, etc – converted to thermal energy when

burned

Types of Potential Energy

Nuclear – energy stored in the nucleus of the atomEx. Fission – splitting nucleii (as in powerplants)

Fusion – combining nucleii of atoms (as in sun with hydrogen atoms)

Fission
