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. The level stays the same






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

5. 9/5T(C)+32






6. Pascal (Pa) or pounds per square inch (psi)






7. The center of an object






8. Mass x velocity






9. An object that is thrown or struck or shot and then travels under the influence of gravity






10. It increases






11. 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).






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






13. Wavelength x frequency






14. If energy is transferred and the internal energy of system B decreases by some amount then the internal energy of system A must incrase by the same amount.






15. Heat is transferred directly through a material with no bulk movement of material






16. Pascal (Pa) or pounds per square inch (psi)






17. The energy that flows from one system to another because of their temperature difference.






18. Kg/m^3






19. Because nothing stops it






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






21. The first to do experimental studies of the laws of motion and was Imprisoned by Pope Urban VIII in 1633 for advocating the Copernican theory - also know as the heliocentric theory - that the earth was a planet revolving around the sun.






22. 18600 miles/sec






23. Weight of displaced water=volume of displaced water in liters x 10 n / liter

25. Heat into system - work done by system






26. Rod with forces applied at opposite ends in the same direction






27. Shows in 1905 that newtons laws were not valid for objects moving with speeds near the speed of light.






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