Review Questions for Energy

Review Questions for Energy 1. Anything that has mass and takes up space (matter) 2. The type of energy that is related to motion or position of matter (mechanical energy) 3. Stored energy (such as that found in fossil fuels) (chemical energy) 4. The SI unit for mass (kilogram) 5. Steam from heated water turns turbines—this is a conversion of what kind of energy to what kind of energy (thermal to mechanical) 6. A material that releases chemical energy when burned (fuels) 7. Energy is neither created nor destroyed—what Law is this? (1st Law of Thermodynamics) 8. A nuclear reactor that is powered by fission reactions to ultimately generate electricity—this is a conversion of what kind of energy to what kind of energy? (nuclear to electrical) 9. Electrical energy results from the movement of ? from place to place? (electrons) 10. The type of fuel formed from decayed plant remains and is the most plentiful fossil fuel in the US is what? (coal) 11. Visible light is a form of what kind of energy? (electromagnetic) 12. This fossil fuel produces the lowest levels of air pollutants (natural gas) 13. A natural resource that is not (or cannot be) replaced as it is used. (Nonrenewable) 14. When you rub your feet on the carpet and then touch the metal desk leg, the shock you get is an example of what kind of energy? (electrical energy) 15. Not available at night. Must be collected from a huge area. Can be expensive. These are all disadvantages of what type of energy? (Solar energy) 16. The vibration and movement of molecules in matter is what kind of energy? (thermal energy) 17. What kind of energy is actually an indirect form of solar energy? (wind energy) 18. Potential energy that depends on height is called what? (Gravitational energy) 19. This is the most widely used renewable energy in the world (hydroelectric) 20. The form of energy that is stored is known as what? (potential energy) 21. Wood, plant matter, and sometimes even waste are all examples of what kind of fuel? (biomass fuel) 22. A rolling ball, a rock falling off a cliff, a person jumping on a trampoline. . .what kind of energy do all three of these have in common (kinetic energy or mechanical energy) 23. The intense heat found under the Earth’s crust is what kind of energy? (geothermal) 24. The form of energy that is associated with motion is known as what? (kinetic energy) 25. Heat released from nuclear fission reactions is used to change water into steam. What is this form of energy called? (Nuclear) 26. The ability to do work is called what? (Energy) 27. A change from one form of energy to another is called what? (Energy transformation) 28. Reducing energy use is what this term means (Energy conservation) 29.
