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.

11. 9/5T(C)+32






12. Solids - liquids - gases






13. Hf






14. Equals total momentum after collision






15. 1 / period (time)






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






17. Force per unit area






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