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






2. Force x lever arm






3. 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.






4. V1 x A1=v2 x A2






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






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






7. T^4






8. Mass x specific heat x temperature change






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






10. 5/9 [T(F)-32]






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






12. Maximum displacement from equilibrium






13. You can't get more work out than the energy you put in






14. ?






15. Why things move






16. Velocity squared / radius






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






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






19. A tendency for liquids to resist flowing.






20. Initial velocity = acceleration x time






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






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






23. A disturbance that propagates through a medium






24. Decreases






25. You cant get as much out as you put in






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






27. Because nothing stops it






28. Speed of light / wavelength






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






30. Net force=0 net torque=0






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






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






33. Voltage / current






34. The center of an object






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






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






37. T^4






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