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






2. 5/9 [T(F)-32]

12. 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).






13. 2p x square root L/g






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






15. Equals total momentum after collision






16. The change in internal energy= the heat absorbed- the work done






17. T^4






18. 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.






19. Pressure x area






20. Wavelength x frequency






21. Time= the square root of 2 x height / acceleration due to gravity






22. A disturbance that propagates through a medium

28. Heat Q= mass of sample x specific heat x temp change






29. P x u x A






30. A disturbance that propagates through a medium






31. Voltage / current






32. The force that brings a system back to equilibrium






33. Velocity squared / radius






34. The center of an object






35. 1 / period (time)






36. Pressure x area






37. Not easy to knock over






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






39. Initial velocity = acceleration x time






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






41. Heat into system - work done by system






42. V x A= constant






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






44. T(C) +273






45. 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.






46. P + density x g h






47. Solids - liquids - gases






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






49. 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.






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