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






2. Force per unit area

8. 100 -000 n/m^2






9. A disturbance that moves through something






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


11. Pressure x area






12. Why things move






13. Equals total momentum after collision






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






15. Length of a wave






16. P + density x g h






17. Time required to complete one cycle






18. The level stays the same

20. It increases






21. A disturbance that moves through something






22. Rod with forces applied at opposite ends in opposite directions






23. Mass x specific heat x temperature change






24. 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).






25. Speed of light / wavelength






26. The total disorder of an object






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

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






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






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






37. The force that brings a system back to equilibrium






38. Initial velocity = acceleration x time






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






40. 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.






41. Decreases






42. Change in velocity / time






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






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