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. Work done / heat in






2. A disturbance that moves through something






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






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






5. Z+n

7. Fluid flow velocity=u - fluid density=p (rho) - fluid pressure=P P +


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).

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






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






34. Current x resistance






35. Not easy to knock over






36. Number density x temperature






37. Net force=0 net torque=0






38. The combination of force and point of application






39. Kg/m^3






40. Current x resistance






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


42. An object that is thrown or struck or shot and then travels under the influence of gravity

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






46. C/n

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






50. V x A= constant
