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. Equals total momentum after collision






2. Believed that the natural state of objects was to be at rest






3. C / f






4. The center of an object






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






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






7. Speed of light / wavelength






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






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






11. C / f






12. Mass x velocity






13. Wavelength x frequency






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






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

16. The first to do experimental studies of the laws of motion and was Imprisoned by Pope Urban VIII in 1633 for advocating the Copernican theory - also know as the heliocentric theory - that the earth was a planet revolving around the sun.






17. A tendency for liquids to resist flowing.






18. 1.25 kg/m^3






19. Maximum displacement from equilibrium






20. The level stays the same






21. C/n






22. Force per unit area






23. The center of an object






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






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






26. Force x lever arm






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






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






29. V1 x A1=v2 x A2






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






31.






32. The total force (positive and negative) acting upon an object






33. 25%






34. Number density x temperature






35. Work done / heat in






36. T^4






37. The total force (positive and negative) acting upon an object






38. Pressure x area






39. Because nothing stops it






40. Maximum displacement from equilibrium






41. Net force=0 net torque=0






42. Sounds above 20 -000 Hz






43. 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.






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






45. 1 -000 kg/m^3






46. Initial velocity = acceleration x time
