Types of Potential Energy
Chemical – energy stored in bonds of atoms
Ex. Biomass, coal, petroleum, etc – converted to thermal energy when burned

Types of Potential Energy
Nuclear – energy stored in the nucleus of the atom
Ex. Fission – splitting nucleii (as in powerplants)
Fusion – combining nucleii of atoms (as in sun with hydrogen atoms)
Fission

Types of Kinetic Energy
Motion energy – energy stored in movement of objects, and released
when objects slowed down
ex. Wind
