Terminal Velocity
The steady final velocity reached by a body in a fluid when the resultant force on it is zero.

Terminal Velocity - The speed with which a body falls through the atmosphere of a planet when the force of gravity pulling it downward is balanced by the force of air resistance ...
terminal velocity (NASA Thesaurus / NASA SP-7, 1965) The maximum velocity attainable, especially by a freely falling body, under the given conditions.
When these larger drops fall (called throughfall) they again may reach terminal velocity and strike the ground with more energy then had they fallen in the open. Terminal velocity of rain drops is reached in about 8 meters.
His work on fluid motion and viscosity led to his calculating the terminal velocity for a sphere falling in a viscous medium. This became known as Stokes' law. Later the CGS unit of viscosity was named a Stokes after his work.
Instead, they typically arrive at the surface at their terminal velocity (free-fall) and, at most, create a small pit. Even so, falling meteorites have caused damage to property, livestock, and even people in historic times.
This is modified by the resistance of the air, which becomes important at higher speeds and usually sets an upper limit ("terminal velocity") to the fall velocity--a much smaller limit for someone using a parachute than one falling without.
I enjoyed hearing how astronaut Story Musgrave ran off to join the Marines and be an airplane mechanic in Korea when he was a kid, how he worked on figuring out the terminal velocity of a free-falling human, and how he got his 10, ...
It occurs in association with other lanthanoids. One of its few uses is as a dopant in solid-state devices.

Terminal Velocity ...
The faster an object falls, the greater is the air resistance acting on it. At a certain velocity, known as the terminal velocity, ...
