Drag:
This is the force that opposes the force of thrust acting on the airplane. Drag is important as it contributes to slowing and landing the aircraft. Drag is generated by every part of the aircraft as it comes into contact with air. There also must be motion between the object, in this case the aircraft, and the air in order for drag to be generated. One equation that can be used to find the force of drag that is generated from the wings of the aircraft is:

The variables involved in determining the Force from drag are:
D= Drag Force, S= Platform Area, ρ= Density of Air, V= Air Velocity, CD= Coefficient of Drag
In order for the airplane to slow down, this force must increase to counter the force created by the thrust of the aircraft. By changing the angle of attack, the amount of drag created by the aircraft can be altered. By increasing the angle, the wing generally will produce more lift , and by decreasing the angle, the wing meets the oncoming air flat, generally causing more drag.
