🪐 Gravity Switcher
Pick a world, then jump, throw or drop. Everything uses that world's real surface gravity.
Surface gravity from NASA's Planetary and Sun Fact Sheets (NSSDCA). Gas giants are measured where the air pressure equals Earth's at sea level, because they have no solid ground. Jumps assume a 0.5 m Earth jump; throws are 10 m/s at 45°; slow worlds play faster than real time so you're not waiting ages.
Gravity pulls on you all the time, and your body keeps fighting it to stay upright. Test your own balance against gravity!
