 Energy is..  The ability to do work Samuel DuPont 2009

 Potential  Kinetic

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

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

 Light  Heat  Sound  Electrical  Motion Samuel DuPont 2009  Chemical

 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

 Example of Heat Energy:  Burning (Fire)  Combustion is another word for Burn Question: What kind of “Work” can heat do for us? CookingKeep us Warm Samuel DuPont 2009

 Example of Sound Energy: Music Did you know: Sound energy can break things like glass Samuel DuPont 2009

 Example of Electrical Energy Lighting We use Electrical energy everyday! Samuel DuPont 2009

 Example of Motion Energy: Windmill Energy of Motion is Everywhere! Moves us aroundBuild things Samuel DuPont 2009

 Energy in Fossil Fuels:  Gasoline  Natural Gas  Oil  Energy in our bodies

 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)
