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






3. The force that brings a system back to equilibrium






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






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






6. 1 -000 kg/m^3






7. Kg/m^3






8. Maximum displacement from equilibrium






9. 25%






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






11. The level stays the same






12. V x A= constant






13. Current x resistance






14. Sounds below 30 Hz






15. Pressure x area






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






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






18. The center of an object






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






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






21. Time required to complete one cycle






22. Maximum displacement from equilibrium






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






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






25. Pressure x area






26. A disturbance that propagates through a medium






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






28. T(C) +273






29. The change in internal energy= the heat absorbed- the work done






30. Initial velocity= the square root of 2gh






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






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