Here's a question I got from one of my students that I would appreciate
your input on: Why does a football, in the case of a long pass, tip
over during the course of its flight so that it is always pointing, to
at least a pretty good approximation, in the direction of its velocity,
Smallest cross sectional area is along the long axis of the ball. As it
decends, aerodynamic forces are at a minimum if the orientation is along
the long axis of the ball.
