DIFFERENT FORMS OF ENERGY
Both potential & kinetic energy come in
many forms.
Use each of the next six slides to complete
your notes.
Write the COMPLETE DEFINITION &
DRAW EACH OF THE ILLUSTRATIONS for
each form of energy.
1.
CHEMICAL ENERGY
Energy in chemical bonds of food, fuel, coal,
batteries, etc.
gasoline/oil
wood
food
coal
battery
2.
ELECTRICAL ENERGY
Moving electrical charges (electrons)
Power outlet

Energy of the moving particles (atoms/molecules)
IN an object
Cold stuff too!
Warm stuff
battery
