There are a variety of diverse forms of energy. The forms of
energy are chemical energy, thermal energy, sound energy, light energy,
electrical energy, and mechanical energy.
-
Chemical
energy is the energy is an energy contained within food, your body, and
fuel.
o
Example: The energy contained in food
-
Thermal energy
is the energy associated with the random motion of particles.
o

heat
-
Sound energy
is the energy produced by the radiation of air particles around a sound
source.
o
Example: A person playing the clarinet
-

-
Nuclear
energy is the energy released from the reaction of the nucleus of
radioactive matters.
o

-
Mechanical
energy is the energy associated with motion.
o
Potential energy is in occurrence when the
object is not touching the surface.
§
