Aerodynamic Forces: Definitions of Lift and Drag

2014-10-6  Drag is a loss that must be overcome with another force, if an object is to move against a stream. A force perpendicular to the stream is called lift. A moment around this axis is called a yaw moment. As the the implies, the sign is usually considered positive, when lift pulls upward.
