terminal velocity



  1. (CLASSICAL MECH) The constant velocity finally attained by a body moving through a fluid under gravity when there is no resultant force acting on it. It is dependent on the shape of the body and the resistance of the air through which it is moving. See also viscosity.

  2. (AERONAUTICS) The hypothetical maximum speed that a body, under given conditions of weight and thrust, could attain along a specified straight flight path, if diving though an unlimited distance in air of uniform density.
