How it works
- Weight force = × Reference gravity; Ideal jump height = v² / (2g); Ideal time above launch level = 2 / g
- Worked example: 70 kg × 1.62 m/s² = 113.4 N; 0.4 m × 9.8 / 1.62 ≈ 2.41975309 m

Assumptions and limitations
Uses rounded NASA reference gravities, including Earth 9.8 and Moon 1.62 m/s². Mass stays unchanged; kilograms on an Earth-calibrated scale are an equivalent reading, not force. Jumps assume constant gravity, no air resistance and return to the launch height. Gas giants have no solid standing surface; their atmospheric reference levels are hypothetical comparisons. Human performance, survival and real landing conditions are not modeled.
