1. ENERGY

2. Class Starter
1) What is energy? 2) Is energy a form of matter? Explain your answer. 3) Try to name 10 different forms of energy.

3. 1) What is energy? Energy is the ability to do work.
Examples of work accomplished by energy:
Making objects move
Making new chemical compounds
Heating substances. .

4. 2) Is energy a form of matter? Explain your answer.
Energy is not considered to be matter. Matter is anything that has a mass and takes up space (volume). Energy does not have a measureable mass or volume.

5. 1) Potential Energy
The energy an object possesses because of its position above a surface.
Potential energy is converted to kinetic energy (moving energy) when an object is dropped.
Examples:
a pencil on a table
a roller coaster waiting to drop

6. Potential energy being converted to kinetic energy

7. The energy of objects in motion.
2) Kinetic Energy
The energy of objects in motion.
Examples:
A bicycle in motion
A moving car

8. 2) Kinetic Energy

9. 3) Elastic Energy
The energy an object possesses when its shape is changed through compression
Examples: A stretched elastic band is stretched or a compressed spring both store elastic energy.

10. 3) Elastic Energy

11. Energy that allows us to see objects around us
4) Radiant Energy
Energy that allows us to see objects around us
Examples: The sun, lights

12. 4) Radiant Energy

13. Energy carried by electrons traveling through a wire
5) Electrical Energy
Energy carried by electrons traveling through a wire
Examples: Electrical energy is used to power most household appliances

14. 5) Electrical Energy

15. 6) Magnetic Energy
Energy stored in the force of 2 magnets’ attraction towards one another
Example: Magnets

16. 6) Magnetic Energy

17. 7) Thermal (heat) Energy
The internal energy of an object due to the motion of its particles (atoms and molecules) of matter. The faster the particles move, the warmer the matter can get. Example: Hot water has a lot of thermal energy because it’s particles move really fast.

18. 7) Thermal (heat) Energy

19. Energy that is released during a chemical reaction
8) Chemical Energy
Energy that is released during a chemical reaction
Examples:
The energy in gas turns car engines.
Your body uses chemical energy contained in food.

20. 8) Chemical Energy

21. Energy contained by the nucleus of atoms
9) Nuclear Energy
Energy contained by the nucleus of atoms
Example: Uranium contains nuclear energy which is used to create energy in nuclear power pants.

22. 9) Nuclear Energy

23. Energy produced when matter vibrates
10) Sound Energy
Energy produced when matter vibrates
Example: Sound waves emitted by a speaker vibrate air particles which make the small bones of your inner ear move. This sends a message to your brain which allows you to hear.

24. 10) Sound Energy
