Energy conservation and energy transfer
Energy does not disappear when we use it. It changes from one form to another.
For example, plants use energy from the Sun to produce glucose, which is stored as chemical (potential) energy. Chemical energy stored in wood (fuel) is converted and released as thermal and radiant (kinetic) energy. Chemical energy in our bodies is converted to kinetic energy to power our muscles and mechanical energy to power the bike.
