# 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. Initial velocity= the square root of 2gh

2. Voltage / current

3. Shows in 1905 that newtons laws were not valid for objects moving with speeds near the speed of light.

4. A disturbance that propagates through a medium

5. T=2p square root m/k frequency= square root k/m;/2p

6. Net force=0 net torque=0

7. V x A= constant

8. P + density x g h
