Subjects : science, literacy
Instructions:
  • Answer 50 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. Rod with forces applied at opposite ends in the same direction

18. Mass x velocity






19. Time= the square root of 2 x height / acceleration due to gravity






20. Rod with forces applied at opposite ends in opposite directions






21. 18600 miles/sec






22. Why things move






23. If energy is transferred and the internal energy of system B decreases by some amount then the internal energy of system A must incrase by the same amount.






24. Mass x specific heat x temperature change






25. 2p x square root L/g

31. Fbottom-Ftop=mg=(density x vol) x g






32. The level stays the same






33. Force x lever arm






34. Heat is transferred directly through a material with no bulk movement of material






35. 9/5T(C)+32






36. Are wider at the base (which lowers their center of gravity)






37. The first to do experimental studies of the laws of motion and was Imprisoned by Pope Urban VIII in 1633 for advocating the Copernican theory - also know as the heliocentric theory - that the earth was a planet revolving around the sun.






38. Pressure x area
