5. Kinetic Energy is
energy that is in
motion. Moving water
and wind are good
examples of kinetic
energy. Electricity is
also kinetic energy
because even though
you can't see it
happen, electricity
involves electrons
moving in conductors.

7. Energy is measured
in the amount of
"work" it does.
Potential Energy is
stored energy.
Examples of
potential energy are
oil sitting in a barrel,
or water in a lake in
the mountains. This
energy is referred to
as potential energy,
because if it were
released, it would
do a lot of work.
8. Energy can change
from one form to
another. A good
example is a Roller
Coaster. When it is on
its way up, it is using
kinetic energy since
the energy is in
motion. When it
reaches the top it has
potential (or stored)
energy. When it goes
down the hill it is
using kinetic energy
again.

10. There are other types of energy as well:
Mechanical Energy is the energy of
motion that does the work. An example
of mechanical energy is the wind as it
turns a windmill.
Heat energy is energy that is pushed
into motion by using heat. An example is
a fire in your fireplace.
Chemical Energy is energy caused by
chemical reactions. A good example of
chemical energy is food when it is
cooked.
Electrical Energy is when electricity
creates motion, light or heat. An
example of electrical energy is the
electric coils on your stove.
Gravitational Energy is motion that is
caused by gravity. An example of
gravitational energy is water flowing
down a waterfall.
11. Kinetic
(≥0), that of the motion of a body
Potential
A category comprising many forms in this
list
Mechanical
The sum of (usually macroscopic) kinetic
and potential energies
Mechanical wave
(≥0), a form of mechanical energy
propagated by a material's oscillations
Chemical
that contained in molecules
Electric
that from electric fields
Magnetic
that from magnetic fields
Radiant
(≥0), that of electromagnetic
radiation including light
12. Nuclear
that of binding nucleons to form
the atomic nucleusonization that
of binding an electron to its atom or
molecule
Elastic
that of deformation of a material (or its
container) exhibiting a restorative
force
Gravitational
that from gravitational fields
Intrinsic, the rest energy(≥0)
that equivalent to an object's rest
mass
Thermal
A microscopic, disordered equivalent of
mechanical energy
Heat
an amount of thermal
energy being transferred (in a
given process) in the direction of
decreasing temperature
Mechanical work
an amount of energy
being transferred in a
given process due to displacement in
the direction of an applied force

14. Potential energies are often measured as positive
or negative depending on whether they are
greater or less than the energy of a specified base
state or configuration such as two interacting
bodies being infinitely far apart.
Wave energies (such as radiant or sound
energy), kinetic energy, and rest energy are each
greater than or equal to zero because they are
measured in comparison to a base state of zero
energy: "no wave", "no motion", and "no inertia",
respectively.
15. Mechanical energy
(symbols EM or E) manifest in
many forms, but can be
broadly classified into
potential energy
(Ep, V, U or Φ) and kinetic
energy (Ek or T). The term
potential energy is a very
general term, because it exists
in all force fields, such as
gravitation, electrostatic and
magnetic fields. Potential
energy refers to the energy
any object gain due to its
position in a force field.
