"The First Law of Thermodynamics says that
energy under normal conditions cannot be created or destroyed, simply
transformed from one type of energy to another. Thus a chemical reaction such as
lighting a match does not create new energy but only converts one type of energy
to another. What's happening with the match is that as the match is burnt,
potential energy is released and converted to heat and light, kinetic energy. In
the cell there are many types of energy transformations: light to
chemical photosynthesis, chemical to chemical(cellular respiration), chemical
to electrical (nervous system), chemical to mechanical(muscles)." Source:

"A
fundamental constituent of matter (e=mc 2 ). 2. The capacity
to do work 3. Kinetic energy (mechanical), potential energy
(gravitational), electrical energy, chemical energy
(molecular, nuclear), radiant energy (light, electromagnetic
radiation) and heat energy." ...Source:
