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.

8. Rod with forces applied at opposite ends in opposite directions






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






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






11. As the speed of a moving fluid increases - the pressure within the fluid decreases
