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.

20. Pressure x area






21. A tendency for liquids to resist flowing.






22. Distance traveled / time






23. 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.






24. The change in internal energy= the heat absorbed- the work done






25. Maximum displacement from equilibrium






26. 11 -000 kg/m^3






27. 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).
