About Physics Quiz
You see lightning before you hear thunder because light travels about a million times faster than sound. The Physics Quiz is full of everyday puzzles like that one: why things fall, float or spin, how energy changes from one form to another, how light bends and sound travels, and how magnets and electricity work. Famous names such as Isaac Newton, Albert Einstein and the Canadian radio pioneer Reginald Fessenden appear along the way, with dates checked and firsts worded carefully. The hard questions ask about laws and units, but the explanations keep them simple.
How to play Physics Quiz
- Press Start for the first of ten questions. The clock starts with it and stops at your last answer.
- Each question asks about forces, energy, light, sound, electricity and magnets.
- Tap an answer, or press 1 to 4 (or A to D) on a keyboard. Answers are final: you see the right one and a one-line explanation, then press Next.
- Most correct answers ranks first, then the fastest time. Only a member’s first finished quiz of the day counts for the leaderboard.
Tips & strategy
- Units carry clues: newtons measure force, joules energy, watts power and hertz how often something repeats.
- Newton’s three laws explain most questions about motion: inertia, force equals mass times acceleration, and action and reaction.
- For light and sound, remember that sound needs something to travel through, while light can cross empty space.
Physics Quiz: questions and answers
Is there any math in the Physics Quiz?
Very little. A few questions use simple formulas, but most are about ideas and everyday examples, explained in one sentence.
Are the history questions checked?
Yes. Dates and firsts were checked against reliable sources, and disputed firsts are worded as “is credited with”.
How many questions does the Physics Quiz have?
158 checked questions: 39 easy, 81 medium and 38 hard. Each day takes ten, easiest first, and a question doesn’t come back until its level has been used up.
