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. A disturbance that propagates through a medium






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






3. Initial velocity= the square root of 2gh






4. 2p x square root L/g






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






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






7. Force per unit area






8. Kg/m^3






9. Equals total momentum after collision






10. Mass x specific heat x temperature change

30. Why things move






31. The level stays the same






32. Current x resistance






33. C/n






34. Change in velocity / time






35. 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.






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






37. 1 -000 kg/m^3






38. The combination of force and point of application

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






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






44. Z+n






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






46. Why things move






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






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






49. Heat is transferred directly through a material with no bulk movement of material






50. 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).
