 What are Newton's Laws of Motion?
Definition
 InertiaAccelerationAction/Reaction
Term
 Law of Inertia
Definition
 A body at rest will remain at rest, and a body in motion will remain in motion at the same speed and in the same direction unless acted upon by an external force.
Term
 Law of Acceleration
Definition
 The force required to produce a change in motion of a body is directly proportional to its mass and rate of change in its velocity.
Term
 Law of Action/Reaction
Definition
 For every action, there is an equal and opposite reaction. When an interaction occurs between two bodies, equal forces in opposite directions are imparted to each body.
Term
 Chord Line
Definition
 The straight line intersecting leading and trailing edges of the airfoil.
Term
 Relative Wind
Definition
 Air in motion equal to and opposite the flight-path velocity of the airfoil.
Term
 Angle of Attack (AOA)
Definition
 The angle measured between the resultant relative wind and the chord line.
Term
 Angle of Incidence(Fixed Wing)
Definition
 The angle between the airfoil chord line and longitudinal axis or other selected reference plane of the airplane.
Term
 Total Aerodynamic Force
Definition
 As air flows around an airfoil, a pressure differential develops between the upper and lower surfaces. The differential, combined with air resistance to passage of the airfoil, creates a force on the airfoil.Lift + Drag
