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. Distance traveled / time






2. 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.






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






4. 18600 miles/sec






5. Work done / heat in

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. Mass x specific heat x temperature change






27. Sounds below 30 Hz






28. 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.






29. Z+n






30. The level stays the same






31. T^4






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






33. The level stays the same






34. A tendency for liquids to resist flowing.






35. A tendency for liquids to resist flowing.






36. Net force=0 net torque=0






37. The heat transfer by electromagnetic waves - thermal light waves






38. Velocity squared / radius






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