Folks, should one not consider that the viscous force *changes* function
with velocity -- at low (what ever that is) the dependence is linear with
velocity, but that dependence gradually changes to quadratic and then to
more complex dependence as velocity increases -- and that all this is
dependent on the *shape* of the object.
