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. Wrote Principia in 1687. Made the 3 laws of mechanics and law of gravity. He also invented calculus.






2. Pressure x area






3. C/n






4. Equals total momentum after collision






5. 5/9 [T(F)-32]






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






7. A tendency for liquids to resist flowing.






8. A disturbance that moves through something






9. 1 / period (time)






10. The amount of heat that is required to raise the temperature of one g of a substance by 1 degree C.






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






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






13. 5/9 [T(F)-32]






14. 11 -000 kg/m^3






15. 2p x square root L/g






16. The level stays the same






17. Kg/m^3






18. Force x lever arm






19. Analized brahe's data and verified the heliocentric theory. These regularities are known as Helpers Laws of Planetary motion.






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

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






24. The center of an object






25. Heat into system - work done by system






26. C / f






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).






28. Sounds above 20 -000 Hz

41. If the temperature of system A is less then the temperature of system B then heat flows from B to A (hot to cold)






42. Heat is carried from place to place by the bulk movement of either liquids or gasses






43. You can't get more work out than the energy you put in
