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. Net force=0 net torque=0






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






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






4. V x A= constant






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






6. A disturbance that propagates through a medium






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






8. Heat into system - work done by system






9. Change in velocity / time






10. Mass x velocity






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

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






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






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






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






27. New theory that explained behavior at the atomic level






28. Time required to complete one cycle






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






30.






31. Pascal (Pa) or pounds per square inch (psi)






32. 5/9 [T(F)-32]






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






34. Because nothing stops it






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






36. Number density x temperature






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






38. Why things move






39.






40. Sounds above 20 -000 Hz
