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.

6. It increases






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






8. 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).






9. Pascal (Pa) or pounds per square inch (psi)






10. 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.
