1. 2. 3. 4. 5. When would the car have the greatest and the least kinetic energy? When would it have the greatest and the least potential energy? 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? What do you think the potential and kinetic energy at points w and x would be based on your answer from #3? What is mechanical energy? 1. What are the different type of energies? 2. Explain what energy is associated with each picture 3. Can you identify any energy transfers? Chemical Energy 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 Electrical Energy The energy of moving electrons • Used to do work • Example: electrical; energy does work on the stereo and the stereo produces sound Sound Energy The energy of an object’s particles vibrating •Ex. Pluck a guitar, vibrate your vocal cords Light Energy Produced by vibrations of electrically charged atoms. • Ex. Microwaves, lasers Nuclear Energy 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
