An artillery shell is fired at, let's say, a 45 degree angle. The shell will rise to a maximun height and then fall back to earth, but the shell will also rotate considerably so that it strikes the ground with the nose forward.
What accounts for the rotation? It would seem that the center of gravity would tend to orient the shell somewhat vertically even with the aerodynamic forces acting on the body. Also, the shell is spinning about its longitudinal axis and this would prevent any rotation.
