Work & Energy Review

4. Energy Energy from the sun
6. Accumulated vegetable and animal wastes.
9. Combustion Engine The combustion process occurs inside the engine.
10. Combustion Fuel is burned outside of an engine and provides heat to another liquid or gas.
13. Engine A spark ignites the gasoline, which is a highly flammable liquid derived from oil.
15. Amount of energy required to move an object. 1 meter using 1 Newton of force.
18. Energy Energy that is stored and used later.
19. Energy Thermal energy stored below Earth's surface.
22. Fission Matter can be changed into energy. The splitting of an atoms nucleus.
23. A circular device with blades.
24. Waste A nuclear power plant produces excess unusable material, which contains unstable atoms that give off radiation.

1. Turbine Engine Use pressurized natural gas, kerosene, or jet fuel as their energy source.
2. Type of biomass
3. Engine Similar to a gasoline engine, except that it burns fuel oil, which is heavier and oilier than gasoline.
5. Energy Energy that is moving.
7. Fossil fuel example
8. Thermal energy that is transferred from something that is warmer to something that is cooler.
11. Energy The energy of the atoms that make up a substance.
12. Fusion The nuclei of two atoms are forced together to form a new nucleus, and a large amount of energy is released.
14. The means by which energy is transferred from one object to another.
16. Generator Converts the mechanical energy into electrical energy.
17. The ability to do work.
18. Cell Solar cell that can turn sunlight into electricity.
20. The rate at which work is done.
21. Fuel Energy rich substance formed from the remains of plants and animals that lived millions of years ago.
