JT>  I've seen this bandied about here, but what does "terminal velocity"
JT>  mean?
If you drop an object, its velocity will increase due to the
gravitational force.  The gravitational force is generally constant.
As the object falls, there will be an opposite force due to drag from
the air flow.  This drag force increases with increasing velocity.
Furthermore, there will be a velocity at which the drag force equals the
gravitational force.  This is an equilibrium condition, and the velocity
at which we define "terminal velocity."
