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.

19. ?






20. 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.






21. The sum of the energy of all the molecules in the system






22. Mass x gravity

38. 1.25 kg/m^3






39. Force per unit area






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






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