Test your basic knowledge |

Subject : engineering
Instructions:
  • Answer 40 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The rate at which work is performed or energy is expended.






2. A collection of wind turbines used to create electricity.






3. The ratio of the useful energy delivered by a dynamic system to the energy supplied to it.






4. Any source of energy that is limited and cannot be replaced when it is used - such as oil - coal - and natural gas.






5. Energy produced by mechanical devices - such as gears - pulleys - levers - or internal combustion engines.






6. Energy visible to the eye.






7. The energy possessed by a body as a result of its motion.






8. The first and simplest element on the periodic table. It is one of the most common elements in the galaxy.






9. The heat equal to 1/180 of the heat required to raise the temperature of one pound of water from 32 degrees Fahrenheit to 212 degrees Fahrenheit at a constant pressure of one atmosphere.






10. The use of flowing water from waterfalls and dams to produce electricity.






11. Gas usually found within the vicinity of petroleum reserves.






12. A resource that can be replaced when needed.






13. Any significant change in measures of climate - such as temperature - precipitation - or wind - lasting for an extended period of a decade or longer.






14. An energy source that will never run out.






15. The phenomenon whereby the earth's atmosphere traps solar radiation - caused by the presence in the atmosphere of gases such as carbon dioxide - water vapor - and methane that allow incoming sunlight to pass through but absorb heat radiated back from






16. Energy stored in the earth in the form of heat.






17. A resource that cannot be replaced once used.






18. A system by which electrical power is delivered throughout a region.






19. A measure of power equal to one joule of work per second.






20. The ability to do work; types include heat - light - sound - chemical - nuclear - mechanical - electrical.






21. Energy derived from wind by means of windmills or wind turbines.






22. Plant materials and animal waste used especially as a source of fuel.






23. Energy can be neither created nor destroyed. There is a fixed amount of energy present in different forms that can be converted from one form to another - but energy does not go away.






24. The flow of electrical power or charge.






25. A natural fuel such as coal or gas formed in the geological past from the remains of living organisms.






26. The process of controlling resources; for example - limiting soil erosion - reducing sediment in waterways - conserving water - and improving water quality.






27. The potential energy locked within a system and released during a chemical reaction.






28. The power of the atom.






29. Refers to the use of resources in ways that prevent their being depleted or permanently damaged.






30. A result of a force moving an object a certain distance.






31. Energy in transit.






32. External surroundings.






33. Oil.






34. Energy associated with the flow of electrons.






35. A device that converts light into electricity.






36. The unit of energy or work in the MKS system of units - equal to the work done by a force of one Newton - meter.






37. A unit measure of work.






38. Energy from the sun.






39. The energy that a piece of matter has because of its position or nature or because of the arrangement of parts.






40. A propeller driven by the wind and connected to a generator. The wind makes it turn the generator - which produces electricity.
