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. A disturbance that moves through something






2. 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).






3. T^4






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