1. Agenda 1/27/10 Forms of Energy (#1). Energy Conversion.
Homework: Forms of Energy Worksheet (#2)
Life Science #6 due next Tuesday

2. Forms of Energy Mechanical Energy:
Definition energy associated with any type of motion.
Examples: Wind, water in a waterfall, running, sound (vibration of matter).

3. Heat Energy:
Definition  The internal motion of particles in matter.
Examples: Rubbing you hands together converts mechanical energy into heat energy.
* Heat flows from a warm object to a cooler object.

4. Chemical Energy:
Definition  Energy found in chemical bonds, releases when bonds are broken.
Examples: Digesting food, when fuel is ignited chemical energy is released.

5. Electromagnetic Energy:
Definition  Moving electric charges.
Examples: Electricity, light, radio waves.

6. Nuclear Energy:
Definition  Energy produced from the splitting or fusion of an atom’s nucleus.
Examples: Nuclear power plants, energy from the sun.

7. Law of Conservation of Energy
Energy can not be created or destroyed (it just changes into another form – conversion).
Example: chemical energy in gasoline is transformed into mechanical and heat energy in an engine.
