A parachutist and a raindrop
An increase in the drag force as velocity increases results in a steady, uniform motion of a body as it falls from a great height in a liquid or gas (e.g. in the atmosphere).
Thus, a parachutist before opening the parachute can gain speed of only up to 50 m/s, and rain drops, depending on their size, reach speeds from 2 to 7 m/s.
