Jump

Same leg power, three very different heights

g = 9.8 m/s²

Same leg push everywhere, a fixed takeoff speed v0v_0. After that, gravity is the only brake:

h=v022g∝1gh = \frac{v_0^2}{2g} \propto \frac{1}{g}

On Earth (g≈9.8 m/s2g \approx 9.8\,\mathrm{m/s^2}), a strong jump peaks around 0.5 m. The Moon (g≈1.62 m/s2g \approx 1.62\,\mathrm{m/s^2}) gives ≈6×\approx 6\times the height, about 3 m. Jupiter (g≈24.8 m/s2g \approx 24.8\,\mathrm{m/s^2}) barely clears ~20 cm.

The dashed line marks each world's expected max.
