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

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






3. Voltage / current






4. Initial velocity = acceleration x time






5. 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.






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






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






8. Initial velocity= the square root of 2gh






9. Hf






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






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






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






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






14. 9/5T(C)+32

21. Length of a wave






22. The combination of force and point of application






23. Number density x temperature

25. ?






26. 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.






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






28. P x u x A

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






34. T^4






35. 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).






36. 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.
