Energy is the ability to do WORK.
WORK is to make something MOVE by applying FORCE to it.
There are 7 Forms of Energy that can cause things to MOVE, or do
WORK.
The 7 Forms of Energy can be remembered using this
acronym:
ACHELMS
ATOMIC ENERGY is the energy created when the NUCLEUS of ATOMS join together or split apart.
ACHELMS
It is also the energy used in nuclear bombs and nuclear
power plants.
• Burning chemicals in fuel to make heat• Using chemicals in batteries to
operate a toy • Digestion of chemicals in food to give
things energy
ACHELMSCHEMICAL ENERGY
the energy stored in a substance that is released
during a chemical reaction.
HEAT ENERGY the energy of the particles (atoms) that make up an object. The
faster the particles move the more heat/THERMAL energy
that is created.
ACHELMSHEAT
ELECTRICAL ENERGY the energy of moving ELECTRONS.
Electrons moving through the wires of radios, TVs, lights and
all electrical appliances are examples of electrical energy.
ACHELMS
LIGHT ENERGY the energy caused by the
vibration of electrically charged
particles. Light/radiant energy is often visible like
sunlight, starlight and electrical lights.
ACHELMSSTARS
MECHANICAL ENERGY the energy of MOVING objects. Any
MOTION or MOVING object has mechanical energy
ACHELMS
• riding a bike
• swinging a hammer
• a spinning windmill
SOUND ENERGY the energy from the vibration of an object. A
guitar string vibrates to make sound. Vocal chords vibrate
make sound. These vibrations cause the air particles to
vibrate.
ACHELMS
ALL 7 Forms of Energy can be either
POTENTIAL OR KINETIC
A guitar string being pulled back is potential
sound energy. When the guitar string is
released, it is changed to kinetic sound
energy.
A CHANGE in one type of energy to another is
called anENERGY CONVERSION
