Everyday Physics

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.

18. Not easy to knock over






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






20. Change in velocity / time






21. 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.






22. You cant get as much out as you put in






23. ?

25. Mass x specific heat x temperature change






26. The heat needed to raise the temperature of 1 pound of water by 1 degree F






27. Gallons per minute (gpm) - liters/s - cubic feet per minute (cfm) or m^3/s

32. Voltage / current






33. Because nothing stops it






34. P(P2-P1)D^4/128Ln n=fluid's viscosity






35. Sounds below 30 Hz






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






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






38. 25%






39. 2p x square root L/g
