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

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






28. P x u x A






29. Velocity squared / radius






30. A disturbance that propagates through a medium






31. The force that brings a system back to equilibrium
