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. Number density x temperature






2. Z+n






3. 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).






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






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






6. ?






7. Current x resistance






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






9. 9/5T(C)+32






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






11. Voltage / current






12. Distance traveled / time






13. C/n






14. The force that brings a system back to equilibrium






15. 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.






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






17. T=2p square root m/k frequency= square root k/m;/2p






18. The level stays the same






19. The amount of heat that is required to raise the temperature of one g of a substance by 1 degree C.






20. The combination of force and point of application






21. 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.






22. T^4






23. Hf






24. T^4






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. C/n






27. Length of a wave






28. The force that brings a system back to equilibrium






29. Change in velocity / time






30. The heat transfer by electromagnetic waves - thermal light waves






31. Mass x specific heat x temperature change






32. 1.25 kg/m^3






33. Equals total momentum after collision






34. The total disorder of an object






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






36. Initial velocity = acceleration x time






37. Distance traveled / time






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






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