1. Forms of Energy

2. What is energy? Ability to do work or cause change Produces Warmth
Produces Light
Produces Sound
Produces Movement
Produces Growth
Powers Technology

3. KINETIC POTENTIAL Classes of Energy Energy of motion
Stored energy or energy of position
Motion, Electrical, Sound, Radiant, Thermal
Gravitational, Stored Mechanical, Nuclear, Chemical

4. Potential Energy
Potential- energy an object has due to position or shape
a stretched rubber band
a popper before it pops
winding a music box

5. Gravitational Energy Potential Energy
-Definition: Energy of position or place
Example: Rock resting at top of a hill
Energy Resource: Hydropower- water in a reservoir behind a dam/waterfalls

6. Stored Mechanical Energy
Potential Energy
Stored Mechanical Energy
-Definition: stored in an object by the application of force
Example: Compressed springs, stretched rubber bands
Energy Resource:

7. Nuclear Energy Potential Energy
-Definition: energy stored in the nucleus of an atom
Fission- the dividing of the nucleus of an atom
Fusion- the joining of the nucleus of atoms
Example: The sun uses fusion to produce light.
Energy Resource: Nuclear Energy

8. Potential Energy Chemical Energy –
-Definition: The energy stored in a substance that can be released when the substance reacts.
Example: Smores: When you burn wood, chemical energy is released. This energy is used to toast marshmallows. The sugar in the marshmallows also has chemical energy that gets absorbed by your body.
Energy Resource: biomass, coal, petroleum, natural gas and propane

9. 2 Types of Energy
Kinetic- energy of motion; all moving objects have kinetic energy
a moving tortoise
a car
you running/walking

10. Mechanical (Motion) Energy
Kinetic Energy
Mechanical (Motion) Energy
-Definition: movement of objects or substances from one place to another
Energy Resource: Wind Energy and Hydropower .

11. Electrical Energy Kinetic Energy
Electrical Energy
-Definition: movement of electrons (negatively charged particles) Electrons move from the electrical outlet through a wire to produce electricity.
Example: Lightning, Electricity
Energy Resource:

12. Sound Energy Kinetic Energy
-Definition: – movement of energy through substances in the form of longitudinal/compression waves
Example: energy from an object is transferred to the air around it causing the air particles to vibrate ultimately causing your eardrum to vibrate allowing you to hear the sound.
Energy Resource:

13. Radiant (light) Energy
Kinetic Energy
Radiant (light) Energy
-Definition: electromagnetic energy that travels in transverse waves
-Example: Can be transmitted through a vacuum
Includes visible light, x-rays, radio waves
Energy Resource: Solar

14. Thermal Energy Kinetic Energy i.e. temperature
-Definition: All matter is made of particles that are continually moving, kinetic energy.
-Example: The higher the temperature, the more kinetic energy, therefore the more thermal energy
The lower the temperature, the less kinetic energy, therefore the less thermal energy
Energy Resource: Geothermal

15. Energy Transfers Law of Conservation of Energy
Energy can not be created or destroyed, only changed/transferred.
