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






2. Hf






3. Fluid flow velocity=u - fluid density=p (rho) - fluid pressure=P P +

9. V1 x A1=v2 x A2






10. The study of how objects behave (from the very tiny to the very big - and from the beginning of the Universe to its ultimate fate).

42. The total force (positive and negative) acting upon an object






43. Wrote Principia in 1687. Made the 3 laws of mechanics and law of gravity. He also invented calculus.






44. Compiled the first detailed observational data on planetary motion (mars) - without a telescope.






45. C/n

47. Heat into system - work done by system






48. You can't get more work out than the energy you put in






49. 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.






50. V x A= constant
