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






2. Heat into system - work done by system






3. V1 x A1=v2 x A2






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

5. Because nothing stops it






6. 10 m/s^2






7. 25%






8. 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).






9. Mass x gravity






10. Time required to complete one cycle






11. 25%






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






13. T^4






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






15. 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.






16. Mass x velocity






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






18. 2 -700 kg/m^3






19. F=mass x acceleration

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






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






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






23. Sounds below 30 Hz






24. The effectiveness of a material in conducting heat






25. 18600 miles/sec






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






27. 1.25 kg/m^3






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

42. Wavelength x frequency






43. Work done / heat in






44. Distance traveled / time






45. A disturbance that moves through something






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

47. Mass x specific heat x temperature change






48. Wavelength x frequency






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






50. Net force=0 net torque=0
