This template calculates terminal velocity of an object given the planet and the altitude from the planet's surface. It assumes that the coefficient of drag is 0.2 and that the cross-sectional area is 1 m2. It also assumes that atmospheric density is equal to the atmospheric pressure multiplied by 1.223125 * 0.008.[1]

Notes

  1. "density as a function of height in this equation is given by 1.223125 x 0.008 x Exp[-height/5000 meters]" [1]
