nutateIt is a common-place of ballistics that a well-spun shell by holding
its attitude near to its initial elevation develops lift as it drops.
It is also well known that the general run of say - pistol bullets
way.markedly about their flight axis and do not develop lift in the same
Would you expect the same thing to happen for a non-spinning cannon ball, a
spherical shape projectile?
... "a small vertical component" of v is probably essential
here. If this is true then a horizontally fired ball must have "initial
lift" equal to zero at any initial velocity. And the lift must increase
in time, at least for a while.
... Is Leigh right that the quadratic F(v)
dependence is not essential and that the same may be expected from the
F=k*v?
