A more accurate dynamic stability criterion which contains the full perturbation term and the correct contribution of gravity is stated independently of the sign of the overturning moment coefficient Km and the presence or absence of non-zero spin. A generalization of the criterion is made by introducing a minimum permissible level of damping which is not necessarily zero. Static and gyroscopic stability are defined and discussed with respect to the dynamic stability criterion. The effect of spin and the location of center of mass on dynamic stabilty are discussed as well as the Kelly-McShane force system.
