20 QUESTIONS · 5 TOPICS · PROJECTILE LAUNCHER · ABOUT 15 MINUTES

Drop a hammer and a feather on the Moon. They land together.

Astronaut David Scott did exactly that on Apollo 15 in 1971, confirming Galileo. Without air, gravity accelerates everything equally. Twenty questions on how the physical world works, each explained, then launch something on four worlds. No sign-up, nothing saved.

A car travels 120 km in 2 hours. What is its average speed?

PROJECTILE LAUNCHER

Launch a ball on four worlds

Ignoring air resistance, a projectile's path is a parabola. Set the angle and speed, then pick a planet. Each launch leaves a trail so you can compare.

0 mticks every 10 m
40.8 mrange
10.2 mmax height
2.9 sflight time
45° gives the maximum range for any speed and gravity.

What this general physics test covers, in short

Twenty multiple-choice questions at upper-secondary to first-year university level, four on each of five topics: motion, forces, energy, waves, and electricity. Most need reasoning more than calculation.

Use g = 9.8 m/s² and ignore air resistance unless stated. The test is our own and not normed. Deeper tests on mechanics, thermodynamics, electromagnetism and quantum physics are coming.
