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.

41. Number density x temperature






42. 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.






43. A disturbance that moves through something






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






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






46. If the CG is above the edge - the object will not fall






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