When the buoyancy effects are taken into account, an object falling through a fluid under its own weight can reach a terminal velocity (settling velocity) if the net force acting on the object becomes zero. When the terminal velocity is reached the weight of the object is exactly balanced by the upward buoyancy force and drag force. That is
A parachutist of the REME Lightning Bolts Army Parachute Display Team lands. The red smoke that gives the parachutists the wind direction during the jump is still running. Changing wind conditions are another risk factor. In conditions of strong winds and turbulence during hot days, the parachutist can be caught in downdrafts close to the ground.

A paratrooper or military parachutist is a soldier trained to conduct military operations by parachuting directly into an area of operations, usually as part of a large airborne forces unit.
If gravity is the only influence acting, then the acceleration [3] is always downward and has the same magnitude for all bodies, commonly denoted . Since all objects fall at the same rate in the absence of other forces, objects and people will experience weightlessness in these situations. Examples of objects not in free-fall:
