Test your basic knowledge |

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 center of an object






2. Force per unit area






3. Not easy to knock over






4. Mass x velocity






5. Force x lever arm






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






7. Work done / heat in






8. Net force=0 net torque=0






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






10. A disturbance that propagates through a medium






11. C / f

13. 100 -000 n/m^2






14. Equals total momentum after collision






15. 18600 miles/sec






16. Length of a wave






17. Equals total momentum after collision






18. Decreases






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






20. C / f






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






22. C/n






23. 1.25 kg/m^3






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






25. Change in velocity / time






26. Gallons per minute (gpm) - liters/s - cubic feet per minute (cfm) or m^3/s






27. Heat into system - work done by system






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






29. It increases






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






31. The total disorder of an object






32. Why things move






33. V x A= constant






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






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






36. Distance traveled / time






37. 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.






38. P x u x A






39. T^4






40. 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).






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






42. Why things move






43. New theory that explained behavior at the atomic level






44. V1 x A1=v2 x A2






45. The combination of force and point of application






46. 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.






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






48. Gallons per minute (gpm) - liters/s - cubic feet per minute (cfm) or m^3/s






49. 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.






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