The lift force FL (also called cross-wind force)
is the component of the wind force FW in the direction
perpendicular to that of the motion of the center of gravity in the plane
of the yaw angle .
The lift force vanishes in the absence of yaw and is the reason for the
drift of a spinning projectile even in the absence of wind.
