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 study of how objects behave (from the very tiny to the very big - and from the beginning of the Universe to its ultimate fate).






2. Not easy to knock over






3. Because nothing stops it






4. The combination of force and point of application






5. 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.






6. Voltage / current






7. Initial velocity= the square root of 2gh






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

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






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






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






12. New theory that explained behavior at the atomic level






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






14. V1 x A1=v2 x A2






15. 1 / period (time)






16. 18600 miles/sec






17. Distance traveled / time






18. Initial velocity = acceleration x time






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






20. Time required to complete one cycle






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






22. The efficiency with which an object emits thermal radiation. Is a number between 0 and 1. A good emitter has an e close to 1.






23. C / f






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






25. Mass x velocity






26. Hf






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






28. The heat needed to raise the temperature of 1 pound of water by 1 degree F






29. Mass x specific heat x temperature change






30. Analized brahe's data and verified the heliocentric theory. These regularities are known as Helpers Laws of Planetary motion.






31. How much torque it takes to get an object rotating






32. 2p x square root L/g

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. 9/5T(C)+32






36. A disturbance that moves through something






37. New theory that explained behavior at the atomic level






38. Current x resistance






39. Equals total momentum after collision






40. Wavelength x frequency






41. P + density x g h






42. Heat into system - work done by system






43. Why things move






44. Mass x velocity






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






46. 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.






47. C / f






48.






49. Number density x temperature
