1. ENERGY BASICS

2. Energy is: The ability to do work, or make a change
2 Types:
KINETIC – Energy of motion
POTENTIAL – Energy of position, or stored energy

3. Newton’s Cradle:

4. Why are the balls slowing down? Is the system losing energy?
NO! ENERGY CAN NEITHER BE CREATED NOR DESTROYED = Law of the Conservation of Energy

5. CHANGED INTO A DIFFERENT FORM
So if energy is not destroyed, it must be:
CHANGED INTO A DIFFERENT FORM
There are seven main types of energy
1.) Mechanical – energy of movement

6. 2. Thermal energy – total amount of energy in the form of heat
3. Sound energy – vibrations that carry energy in waves

7. 4. Nuclear energy – energy stored in atoms
5. Chemical energy – energy stored in chemical bonds (food, gas, battery)
4. Nuclear energy – energy stored in atoms

8. 6. Electrical energy – energy carried by electrical current
7. Radiant energy – energy carried by light waves

9. II. Energy Transformations
A. Energy is constantly changing from one form to another. This change is called an Energy Transformation.

10. 1. Chemical energy in gasoline is transformed into mechanical energy in the engine of the car.
2. Electrical energy is transformed into sound energy inside your stereo.
