5 CHAPTER 9 DIRECTED READING WORKSHEET Energy and Energy Resources As you read Chapter 9, which begins on page 212 of your textbook, answer the following questions. Strange but True! (p. 212) 1. What vast treasure-troves have been buried at sea for millions of years? a. gold c. salt b. gas hydrates d. sodium bicarbonate 2. Scientists suspect that large areas off the coasts of North Carolina and South Carolina may contain 70 times the natural gas consumed by the United States in 1 year. 3. What happens when you hold a flame near icy formations of water and methane? The methane ignites, making the hydrate look like a burning ice cube. What Do You Think? (p. 213) Answer these questions in your ScienceLog now. Then later, you ll have a chance to revise your answers based on what you ve learned. Investigate! (p. 213) 4. What will you find out in this activity? I will find out what happens when energy stored in matter is released. Section 1: What Is Energy? (p. 214) 5. Where do you think energy is being transferred as the tennis game is played? Accept all answers. Students will learn more about the transfer of energy as they work through the section.

6 7. When you hit a tennis ball with a racket, energy is transferred from the racket to the ball. True or False? (Circle one.) 8. Work and energy are both measured in joules. Kinetic Energy Is Energy of Motion (p. 215) 9. Does the tennis player have kinetic energy if she isn t moving? Explain. Sample answer: Yes; the tennis player is still breathing, her eyes are blinking, and her heart is beating. So she still has kinetic energy even if she s standing still. 10. In Figure 2, on page 215, swinging a hammer gives the hammer energy to do work. True or False? (Circle one.) 11. Which of the following have kinetic energy? (Circle all that apply.) a. a falling raindrop c. a plane in the sky b. a rolling bowling ball d. a parked car 12. Which of the following is NOT true of kinetic energy? a. The faster something moves, the more kinetic energy it has. b. The lower the mass is, the higher the kinetic energy. c. Speed has a greater effect on kinetic energy than mass has. 13. The truck and the red car in Figure 3, on page 215, are traveling at the same speed. So why does the truck have more kinetic energy? The truck is more massive, so it has more kinetic energy. Potential Energy Is Energy of Position (p. 216) 14. Why does a stretched bow have potential energy? The bow has potential energy because work was done on it to change its shape. 62 HOLT SCIENCE AND TECHNOLOGY
7 15. Take a moment to look at Figure 5, on page 216. Which of the following would have more gravitational potential energy than a diver on a platform? (Circle all that apply.) a. a diver with the same mass on a lower platform b. a diver with the same mass on a higher platform c. a diver with more mass on the same platform d. a diver with less mass on the same platform 16.

Potential energy plus gravitational energy equals mechanical energy. True or False? (Circle one.) Review (p. 217) Now that you ve finished the first part of Section 1, review what you learned by answering the Review questions in your ScienceLog. Forms of Energy (p. 218) 19. List the six forms of energy. thermal, chemical, electrical, sound, light, and nuclear 20. The total potential energy of all the particles in an object is known as thermal energy. True or False? (Circle one.) 21. In Figure 7, on page 218, the particles in ocean water have less kinetic energy than the particles in steam. Why? The particles in ocean water have less kinetic energy than the particles in steam because the particles of steam move around more rapidly than the particles in ocean water.
