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.

9. A disturbance that propagates through a medium






10. Fbottom=Ftop+mg where mg is the weight of the volume






11. The study of heat and its transformation into mechanical energy






12. 1 / period (time)






13. Fbottom-Ftop=mg=(density x vol) x g
