a direction perpendicular to that flow, the force required to
do this work creates an equal and opposite force that is lift.
The object may be moving through a stationary fluid, or the
fluid may be flowing past a stationary object—these two are
effectively identical as, in principle, it is only the frame of
reference of the viewer which differs. The lift generated by
an airfoil depends on such factors as:
• Speed of the airflow
• Density of the air
• Total area of the segment or airfoil
• Angle of attack (AOA) between the air and the airfoil
