Energy Study Guide Name____________________________________ Class __________________ Date __________________ Word Bank: Some will be used more than once. Conservation Mechanical Potential Efficiency Kinetic Lower Electromagnetic Nuclear Sound Light Form Higher Energy Law of Conservation of Energy 1. The ability to cause change is called ________________________________________ 2. In what situation would you have the most kinetic energy: sitting, standing, walking, or running? _______ 3. The energy stored in food is a form of ________________ energy. 4. A type of energy stored in the nucleus of an atom is called _______________ energy. 5. A law stating that no matter how energy is transferred or transformed, it continues to exist in one form or another is known as _____________________________________________________________________ 6. Chris's new clothes dryer is more energy efficient than his old one. This means that it loses a _________ percentage of energy to unwanted forms. 7. When a rock falls from a cliff, potential energy changes into ________________ energy because it is moving. 8. Which of these is a form of energy: light, a molecule, darkness, or an atom? ________________________ 9. Which of these is a form of electromagnetic energy: motion, food, light, or noise? ___________________ 10. X-rays are a form of ____________________________ energy. 11. Tom moves a bag of groceries from the floor to the table. By moving the bag, he has increased the bag's __________________ energy. 12. When Jamal plays the trumpet, mechanical energy is converted into ______________ energy. 13. As a yo-yo moves down and up its string, potential energy changes into ______________ energy and then back again to potential energy. 14. For chemical energy to be used for some purpose, it must convert into a different __________ of energy. 15. The law of _______________________ of energy states that energy can neither be created nor destroyed. 16. Some electrical energy entering a vacuum cleaner is converted to heat and sound. The percentage of energy used for cleaning carpets is the vacuum's energy _____________________. 17. An apple tree converts ________________ energy from the Sun into chemical energy. 18. An electrical generator can use falling water to convert _________________ energy into electrical energy. 19. Laura is riding a swing. She swings up high to the back and stops for an instant. She then swings down towards the center and up high to the front, where she stops again for an instant. Describe this as a conversion between potential and kinetic energy. You can draw a picture to help you if you need to. 20. Judy shoots a rubber band toward a tree. In a short paragraph, explain what energy conversions happen when she shoots the rubber band. Use the terms potential energy, kinetic energy, and convert in your answer.
