POTENTIAL ENERGY
Potential energy is the stored energy an
object has due to its position.
GRAVITATIONAL POTENTIAL
Gravitational potential energy is
the stored energy an object has
due to the possibility that gravity
could cause it to fall.
CHEMICAL POTENTIAL ENERGY
Chemical energy is energy that is
stored in chemical compounds
(atoms and molecules). The
energy is released when the
bonds are broken.
ELASTIC POTENTIAL
Elastic potential energy is
the stored energy an object has
due to being stretched or
Compressed.
NUCLEAR POTENTIAL ENERGY
Nuclear energy is energy released
when atoms split or combine, which
is respectively called fission and
fusion.
KINETIC ENERGY
Kinetic energy is energy in motion.
ELECTRICAL ENERGY
Electrical energy is energy that is
caused by the movement of
charged particles in an electrical
field.
SOUND ENERGY
Sound energy is the movement
of energy through longitudinal
waves that travel in a medium
such as water, air, or solids.
3. Student Discussion: Why are these
pictures examples of sound energy?
Can these pictures be examples of any
other forms of energy?
HEAT (Thermal) ENERGY
Heat energy is the energy caused
by moving particles. Heat energy
always flows from warmer to
cooler.
LIGHT ENERGY
3. Student Discussion: Why are
these pictures examples of light
energy? Can these pictures be
examples of any other forms of
energy?
Light energy is radiant energy
that contains light you can see.
Light energy can travel through
space, where sound can’t. The
different kinds of light waves are
part of the electromagnetic
spectrum. Light can be
absorbed, reflected or refracted.
