Re: The drag force -- a correction squared

He is quite correct that *at terminal velocity* the drag force is
proportional to the mass. He *never* claimed that the drag force was
proportional to the mass as a function of velocity. Rather, only that
*at* the terminal velocity, whatever it happens to be, the drag force
*is* proportional to the object's mass simply because *at* the terminal
velocity the drag force equals the object's weight, and the weight *is*
proportional to the mass where the gravitational field strength is the
proportionality constant.

David will forgive me for reminding him I hope, that using maths
for support, I can show it is ABSOLUTELY TRUE that the population of
Sri Lanka is strongly correlated with the change in US Stock market
values over the last six or seven years.
It is not only perfectly correct, and quite clear as I stated it,
but totally misguided in terms of causality, in fact!
