Download Conservation of Energy

Conservation of Energy
1. What is the law of conservation of energy?
2. Explain the law of conservation of energy using an example from you own life.
3. Consider a ball thrown straight up in the air. At what position is the KE at
maximum? Where is the PE at maximum? Explain.
4. A physical Science teacher demonstrates energy conservation by
releasing a heavy pendulum bob near his chin. What would happen if in
his exuberance, he gave the bob a slight shove as it left his chin?
5. Discuss the design of the roller coaster
shown in the sketch in terms of the conservation of
energy.
6. On a slide a child has potential energy that decreases by
1000j, while her kinetic energy increases by 900j. What
other form of energy is involved, and how much?
7. Consider the identical balls rolling on
each track shown, when they reach
the end of the track, which will have
great speed? Explain.
8. Complete the following…
9. A friend says the energy of oil and coal is actually a form of solar
energy. Make a case to backup your friends views (coal & oil is very old organic matter)
10. What is the ultimate source of windmill & hydroelectric energy? Explain.
11. Draw a diagram that traces back the energy you use throughout the day to a single
source. (be sure to include arrows showing direction of energy flow, sketches & labels)
