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. T(C) +273






2. The effectiveness of a material in conducting heat






3.






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






5. 2p x square root L/g






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






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






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






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






10. Sounds below 30 Hz






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






12. Change in velocity / time






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






14. 100 -000 n/m^2






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






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






17. Change in velocity / time






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






19. The force that brings a system back to equilibrium






20. If the CG is above the edge - the object will not fall






21. Force x lever arm






22. Mass x velocity






23. Wavelength x frequency






24. A disturbance that moves through something






25. The efficiency with which an object emits thermal radiation. Is a number between 0 and 1. A good emitter has an e close to 1.






26. Why things move






27. Because nothing stops it






28. V x A= constant






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






30. 2 -700 kg/m^3






31.






32. Compiled the first detailed observational data on planetary motion (mars) - without a telescope.






33. A disturbance that moves through something






34. 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).






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






36. Distance traveled / time






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






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






39. Wavelength x frequency






40. A tendency for liquids to resist flowing.






41. Speed of light / wavelength






42. Velocity squared / radius






43. Equals total momentum after collision






44.






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






46. 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.






47. 100 -000 n/m^2






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






49. Tube cross section area A - flow speed u vfr= u x A (m/s x m^2)






50. 2 -700 kg/m^3
