terminal velocity[′tər·mən·əl və′läs·əd·ē]
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.
The maximum velocity attainable, especially by a freely falling body, under given conditions. Also known as terminal speed.
