Energy
I.
What is energy?
*Energy- the ability to do work
a. can change from one type to another (potential to kinetic to potential)
II.
TWO TYPES OF ENERGY
a. Potential energy- energy an object has because of position.
1. Examples: sitting at the top of the slide, at the highest point of the swing set while
swinging (that split second after you go up you stop to come back down)
b. Kinetic energy- energy of motion
1. Examples: sliding down the slide, swing moving downward

1. Mechanical energy- a kind of energy an object has because it can move or is moving
a. it can be kinetic or potential
b. Example: when a bicycle move it changes from potential to kinetic mechanical energy
2. Chemical energy- enegy that comes from chemical changes
a. is potential
b. Examples: gasoline, batteries, coal
3. Electrical energy- energy that comes from the flow of electricity
a. Examples: merry-go-round, Ferris wheel, radio
4. Light energy- an energy source that keeps us warm and lets us see
a. Examples: sun, candle, light bulb, rainbows, flashlight
5. Heat energy- a form of energy that is transferred by a difference in temperature
a. Examples: hot cup of tea, fire, volcano
6. Sound energy- a form of energy that is produced by sound waves
a. Examples: radio, television
