1. 1. When would the car have the greatest and the least kinetic energy? 2. When would it have the greatest and the least potential energy? 3. If the potential energy at Y was 30,000 j and the Kinetic energy was 40,000 j, what is the mechanical energy of the cart? 4. What do you think the potential and kinetic energy at points w and x would be based on your answer from #3? 5. What is mechanical energy?

2. 1. What are the different type of energies? 2. Explain what energy is associated with each picture 3. Can you identify any energy transfers?

3. The energy stored in atoms and compounds (potential energy) Found in starch and sugar (food)- our bodies source of energy Found in oil and gas- our homes and cars source of energy Chemical Energy

4. The energy of moving electrons Used to do work Example: electrical; energy does work on the stereo and the stereo produces sound Electrical Energy

5. The energy of an object’s particles vibrating Ex. Pluck a guitar, vibrate your vocal cords Sound Energy

6. Produced by vibrations of electrically charged atoms. Ex. Microwaves, lasers Light Energy

7. The nucleus of an atom splits giving off energy Used to generate electrical energy at nuclear power plants Life would not be possible without the nuclear energy of the sun. The sun is our most important energy resource Nuclear Energy
