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. 10 m/s^2

6. The combination of force and point of application






7. 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.






8. Force per unit area






9. 1.25 kg/m^3






10. 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).






11. Wavelength x frequency






12. Why things move






13. A disturbance that moves through something






14. Current x resistance






15. Equals total momentum after collision






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






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






18. Mass x velocity






19. Mass x velocity






20. Equals total momentum after collision






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






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






23. 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.






24. Not easy to knock over






25. Force x lever arm






26. Initial velocity= the square root of 2gh






27. Mass x gravity






28. The combination of force and point of application






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






30. Work done / heat in






31. Fbottom-Ftop=mg=(density x vol) x g






32. The amount of heat that is required to raise the temperature of one g of a substance by 1 degree C.






33. A disturbance that propagates through a medium






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






35. Solids - liquids - gases






36. 1 / period (time)






37. 2 -700 kg/m^3






38. Force per unit area

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






43. T(C) +273






44. The sum of the energy of all the molecules in the system






45. Fbottom=Ftop+mg where mg is the weight of the volume
