Potential energy. Potential energy is stored energy and the energy of position. Kinetic energy. Kinetic energy is the motion of waves, electrons, atoms, molecules, substances, and objects. Chemical energy is energy stored in the bonds of atoms and molecules. Batteries, biomass, petroleum, natural gas, and coal are examples of chemical energy. Chemical energy is converted to thermal energy when people burn wood in a fireplace or burn gasoline in a car's engine.
