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 study of how objects behave (from the very tiny to the very big - and from the beginning of the Universe to its ultimate fate).






2. 10 m/s^2






3. Initial velocity = acceleration x time






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






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






6. ?






7. 5/9 [T(F)-32]






8. Speed of light / wavelength






9.






10. V1 x A1=v2 x A2






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






12. C/n






13. A disturbance that propagates through a medium






14. The total disorder of an object






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






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






17. Time required to complete one cycle






18. Why things move






19. P x u x A






20. Kg/m^3






21. Net force=0 net torque=0






22.






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






24. 25%






25. 100 -000 n/m^2






26. Voltage / current






27. Mass x specific heat x temperature change

33. Time required to complete one cycle






34. 2p x square root L/g






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






36. Why things move






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






38. 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.






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






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






41. 11 -000 kg/m^3






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






43. V x A= constant






44. Speed of light / wavelength






45. Sounds below 30 Hz






46. Wavelength x frequency






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






48. Current x voltage energy/time (joules per second)






49. 18600 miles/sec






50. Not easy to knock over
