1. Notes 10.1: Energy Flow

2. Law of Conservation of Energy
Energy can’t be created or destroyed, just transferred from one form to another.
A Rube Goldberg machine is an example of energy transfer in a closed system.

3. Forms of energy:
Mechanical Energy
Kinetic
Potential (gravitational, rubber bands, springs)
Work

4. Electromagnetic energy (EM Spectrum)
Radiant Energy
Electromagnetic energy (EM Spectrum)
Light, infrared, UV, X-rays , etc.

5. Electrical Energy
Flow of electrical current

6. Energy stored in bonds that join atoms
Chemical Energy
Energy stored in bonds that join atoms
Gasoline, food

7. Nuclear Energy
Fusion – combining nuclei (stars)
Fission – splitting nuclei (power plants)

8. Thermal Energy
Heat is the flow of this energy
Can be used to do work

9. Remember:
You can’t get more energy out than is put in.
There is no such thing as free energy.
Perpetual motion is impossible due to the effects of friction.
