1. AC HELMS

2. 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.

3. The 7 Forms of Energy can be remembered using this acronym:
ACHELMS

4. It is also the energy used in nuclear bombs and nuclear power plants.
ACHELMS
ATOMIC ENERGY is the energy created when the NUCLEUS of ATOMS join together or split apart.
It is also the energy used in nuclear bombs and nuclear power plants.

5. ACHELMS CHEMICAL ENERGY
the energy stored in a substance that is released during a chemical reaction.
Burning chemicals in fuel to make heat
Using chemicals in batteries to operate a toy
Digestion of chemicals in food to give things energy

6. ACHELMS
HEAT
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.

7. ACHELMS
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.

8. 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.
STARS

9. ACHELMS
MECHANICAL ENERGY the energy of MOVING objects. Any MOTION or MOVING object has mechanical energy
riding a bike
swinging a hammer
a spinning windmill

10. ACHELMS
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.

11. 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.

12. A CHANGE in one type of energy to another is called an
ENERGY CONVERSION
