This template calculates terminal velocity of an object given a planet's mass (M), the distance from the object to the planet's center (r), and the atmospheric pressure (pressure) at the object's location, specified in units of 1 atm (the pressure at sea level on Kerbin). It assumes that the coefficient of drag is 0.2 and that the cross-sectional area is 1 m².
