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. 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).






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






3. Initial velocity= the square root of 2gh






4. Maximum displacement from equilibrium






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

6. 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.






7. A disturbance that moves through something






8. New theory that explained behavior at the atomic level






9. 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.
