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. A tendency for liquids to resist flowing.






2. How much torque it takes to get an object rotating






3. A disturbance that propagates through a medium






4. Mass x gravity






5. Heat is carried from place to place by the bulk movement of either liquids or gasses






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






7. The force that brings a system back to equilibrium






8. 2p x square root L/g






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