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.

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






13. 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.






14. Maximum displacement from equilibrium






15. Not easy to knock over






16. 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.






17. Heat is carried from place to place by the bulk movement of either liquids or gasses






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






19. Voltage / current






20.

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






23. Sounds below 30 Hz






24. A tendency for liquids to resist flowing.






25. 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.






26. Wrote Principia in 1687. Made the 3 laws of mechanics and law of gravity. He also invented calculus.






27. Change in velocity / time






28. Distance traveled / time

46. Wavelength x frequency






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






48. 1 / period (time)






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






50. The study of heat and its transformation into mechanical energy
