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. Current x voltage energy/time (joules per second)






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






3. C/n






4. Why things move






5. 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).






6. Sounds below 30 Hz






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






8. 25%






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






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






11. ?






12. Mass x velocity






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






14. Believed that the natural state of objects was to be at rest






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






16. 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.






17. Speed of light / wavelength






18. V x A= constant






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






20. Kg/m^3






21. Mass x gravity






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