## terminal velocity

1. the constant maximum velocity reached by a body falling under gravity through a fluid, esp the atmosphere
2. the maximum velocity that an aircraft can attain, as determined by its total drag

## terminal velocity

[′tər·mən·əl və′läs·əd·ē]
(fluid mechanics)
The velocity with which a body moves relative to a fluid when the resultant force acting on it (due to friction, gravity, and so forth) is zero.
(physics)
The maximum velocity attainable, especially by a freely falling body, under given conditions. Also known as terminal speed.

## terminal velocity

In an air-conditioning system, the average velocity of an airstream at the end of its throw; one of the indicators of drafty conditions and comfort level.

## terminal velocity

The maximum speed a freely falling object can reach when falling through the air. In an aircraft, it is the maximum velocity at which the drag has reached an amount in which the aircraft will not continue to accelerate downward.
