Forms of Energy
Potential or Kinetic
All forms of energy fall
under two categories
Potential:
Stored energy
Energy of position

Gravitational
Kinetic
Energy of motion
Waves,electrons,atoms,
molecules, and
substances

Matter
All matter is made up of particles in
motion. Because the particles are in
motion, they have kinetic energy. At
higher temperatures particles move
faster and therefore have more kinetic
energy.
Ice---- Water---
Steam
Thermal Energy
Thermal Energy (or heat) is the
internal energy in substances-the
vibration and movement of atoms and
molecules within the substance.
Geothermal energy is an example of
thermal energy.
Heat is
energy created
by the vibration
and movement
of molecules.
Chemical Energy
Chemical Energy is the energy of a
compound that changes as the atoms
are rearranged.
Chemical energy is a form of stored or
potential energy.
We eat grow.
The more atoms that are bonded
together in a compound, the more
potential energy that compound has.
Wood has stored chemical
energyburnsheat
Chemical energy is the energy stored in the
bonds of atoms and molecules.
Biomass, petroleum, natural gas, propane,
and coal are examples of stored chemical
energy.
It takes energy to grow---Chemical Energy
stored in simple sugars. The energy to make
these sugars comes from light energy. Most of
this light energy comes from the sun. Plants
absorb the light energy and store it in their
leaves, stems, fruits, and roots as chemical
energy. They use the energy to grow! When we
eat plants, or animals that eat plants, we absorb
the chemical energy so we can grow!
Electrical Energy
Electrical energy is the movement of
electrons.
Lightning & electricity are examples of
electrical energy.
Electrical Energy
Because electricity is created by the
changing positions of magnets, electricity
can be considered a form of potential energy.
When a device is plugged into an
outlet and turned on, electrons
move back and forth within the
wires of the cord, so electrical
energy is also considered Kinetic
energy too.
Sound Energy
Sound Energy
Sound is the movement of energy
through substances (solid, liquids, &
gases) in longitudinal
(compression/rarefaction) waves.
Sound Energy
Is both potential and
kinetic.
To make an object
vibrate, work must be
done.
 You change the position
therefore you create
potential energy.
 When released, the
movement (vibration) is
passed to air
particles=kinetic energy.

Radiant Energy (Light)
Radiant Energy
Radiant energy is electromagnetic
energy that travels in transverse waves.
Radiant energy includes visible light, xrays, gamma rays, and radio waves.
Solar energy is an example of radiant
(Light) energy.
The Electromagnetic Spectrum
Transverse Wave:
Nuclear energy
Nuclear energy is energy in the
nucleus (core) of an atom. Atoms
are tiny particles that make up
every object in the universe.
There is enormous energy in the
bonds that hold atoms together.
Nuclear energy
• Nuclear energy can be used to make
electricity. First, the energy must be
released! It can be released in two
ways: Nuclear fusion and nuclear
fission.
Nuclear fusion
In nuclear fusion, energy is released when
atoms are combined or fused together to
form a larger atom. This is how the sun
produces energy.
Nuclear fission
During nuclear fission, a small particle called a
neutron hit the uranium atom and it splits, releasing a
great amount of energy as heat and radiation.
This caused more neutrons to be released
to go on and bombard other
uranium atoms, and the process
repeats itself over and over.
This is called a chain reaction.
