ENERGY
Energy – The ability to do work
How is energy involved in the
following picture?
STATES OF ENERGY
1. Kinetic - The energy of motion,
when energy is being
transferred.
STATES OF ENERGY
2. Potential - Stored Energy or energy
that is waiting to be
transferred.
What type of energy does each
picture demonstrate?
The Roller Coaster
7 Forms of Energy
FORMS OF ENERGY
1. Mechanical –
Examples of mechanical energy
FORMS OF ENERGY
2. Thermal –
Results from friction, causes temperature
and phase changes, ALL OTHER TYPES of
energy TURN INTO THIS.
Solid to Liquid
Liquid to Gas
FORMS OF ENERGY
3. Chemical –
Examples: All forms of fuel (gasoline,
coal, wood, food, radioactive
materials) Photosynthesis, batteries.
What are examples of
Chemical Energy in this picture?
1. Wood Burning;
2. Chemical energy is stored in the
marshmallow’s sugar molecules.
3. When you eat a marshmallow,
FORMS OF ENERGY
4. Electrical Energy –
The electrical outlets
in your home allow
you to use electrical
energy
FORMS OF ENERGY
5. Sound –
Example: Guitar Strings Vibrating
FORMS OF ENERGY
6. Light –
LIGHT IS
ELECTROMAGNETIC
ENERGY
Electromagnetic Spectrum
Other Examples of Electromagnetic Energy
FORMS OF ENERGY
7. Nuclear –
Examples:
Sun’s Energy
Nuclear Power Plant
WHICH FORM OF ENERGY IS REPRESENTED
IN EACH PICTURE?
SIMPLE
ENERGY CONVERSIONS
A change from one form of energy to
another is called an ______________.
Any form of energy can be converted
Into any other form of energy.
ENERGY CONVERTING FROM
POTENTIAL TO KINETIC
MAX
PE.
MAX
PE.
MAX
KE.
CHEMICAL ENERGY CONVERSIONS
1. Chemical energy
2. Mechanical energy
3. Heat
Chemical  mechanical  thermal (heat)
Examples of Other
Chemical Energy Conversions
1. Batteries(chemical)
2. Gas(chemical) 
Chemical to ?
Electrical Energy Conversions
All electrical appliances are converting
electricity.
Name several examples of electrical
conversions.
MECHANICAL ENERGY CONVERSIONS
Movement causes friction which
causes heat. Mechanical can turn
into mechanical again.
Bike: mechanical  mechanical
thermal  sound
THERE HAS TO BE AN ENERGY CHANGE TO MAKE THINGS
HAPPEN!
ENERGY CONVERSIONS
CONSERVATION OF ENERGY
The Law of Conservation of Energy states
Energy cannot be Created or Destroyed.
Energy Resources – a natural resource that can
be converted into energy for use by humans.
Two Types of Energy Resources:
Renewable & Nonrenewable
Renewable Resource – an energy resource
that can be replaced in a short amount of time.
Renewable Resources:
1. Hydropower
2. Wind
3. Geothermal
4. Biomass
5. Solar power
Nonrenewable Resources – cannot be replaced
after use or takes millions of years to replace.
Fossil Fuels – energy resources that are
formed from plants and animals that
lived millions of years ago
Non Renewable Resources:
1. Coal
2. Natural Gas
3. Petroleum
4. Propane
5. Uranium
COMPLEX
ENERGY CONVERSIONS
Converting energy from the sun to
make it available for use at your home.
Complex Energy Conversions
All energy originates (starts) with the
SUN!!!!
HOW CAN WE MAKE ENERGY FROM THE SUN
USEABLE????
The energy conversions involved with the sun are:
How can we use the light energy given from the sun on
earth?
Nuclear Power
Disadvantage:
Solar Power
