(I thought John Mallinckrodt's observation about a retarding force
having a greater than first power velocity dependence providing
effective lift to be a revelation here. I'd never heard of such a
thing, but it is obviously true - and significant. It explains for
me why bullets fired from a rifle don't fall with acceleration g.
I have written an authority for information on this topic and I
will, of course, share it when I get it.)
I am very much looking forward to this information. The notion of the
retarding force being proportional to v-squared is an approximation, and
I have seen that approximation used only for calculating the force
opposite to the direction of motion. I wonder if the lift effect is a
reflection of the data or only a case of a limited model being applied
outside of its range of validity.
