What is Energy?
Energy is.. The ability to do work

Potential Energy
Potential Energy: Stored Energy
Can you think of any other forms of potential energy?

Kinetic Energy
Energy in “Motion”
Jumping out of a plane
Can you think of any other forms of Kinetic energy?

Are there different forms of energy? Light Heat Sound
Electrical Motion

I see the Light! Example of Light Energy:
The Sun Question?
Does the sun also have another form of energy?
HEAT!
Fun Fact:Plants use light energy to grow!
Samuel DuPont 2009

Is it getting Hot in here? Example of Heat Energy:
Burning (Fire) Combustion is
another word for Burn
Question:What kind of “Work” can heat do for us?
Cooking Keep us Warm
Samuel DuPont 2009

Sounds like energy to me
Example of Sound Energy:
Music
Did you know:Sound energy can break things like glass

Now this is Electric! Example of Electrical Energy
Lighting
We use Electrical energy everyday!

How can Energy move me?
Example of Motion Energy:
Windmill
Energy of Motion is Everywhere!
Moves us around
Build things

Chemical Energy
Energy in Fossil Fuels: Gasoline Natural Gas Oil
Energy in our bodies

Chemical Energy Most Chemical Energy is converted into other forms
of energy: Gasoline Heat Food Motion
Other forms of energy change as well Light Electricity (Solar) Gasoline Motion (Car) Electricity Light (light bulb)
