Re: The drag force -- a correction squared



When Ludwik wrote:


Unlike in psychology, r>0.99 are quite common in physics. For
example, when we plot measured values of terminal speeds versus
masses of falling objects.

it surely marked a significant shift in the thread.

To date we have been discussing whether drag force is related to mass
and shown that in the common but special case where the object is
travelling at terminal speed there is a relation.

The question of a relation between the value of the terminal speed
itself and the mass of an object is a different one. I expect the
relation to vary from object to object depending on the size and shape
of the object and on what power of the speed the drag depended on.
