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. Wavelength x frequency






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






3. Rod with forces applied at opposite ends in the same direction

16. 25%






17. A disturbance that moves through something






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






19. 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).






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






21. T(C) +273






22. Because nothing stops it

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






26. Sounds above 20 -000 Hz






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






28. Velocity squared / radius






29. Force per unit area






30. New theory that explained behavior at the atomic level

35. A disturbance that moves through something






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






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






38. 1 / period (time)






39. A tendency for liquids to resist flowing.






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






41. Length of a wave






42. Because nothing stops it






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






44. 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.






45. 18600 miles/sec






46. 1.25 kg/m^3






47. Current x resistance

49. Not easy to knock over






50. 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.
