The term "free fall" is often used more loosely than in the strict sense defined above. Thus, falling through an [[atmosphere]] without a deployed parachute, or lifting device, is also often referred to as free fall. The aerodynamic drag forces in such situations prevent them from producing full weightlessness, and thus a skydiver's "free fall" after reaching [http://en.wikipedia.org/wiki/Terminal_velocity terminal velocity] produces the sensation of the body's weight being [[supported]] on a cushion of air.
