Explain how relative wind, angle of attack, center of lift, and laminar flow affect the performance of an airfoil.

Explanation may include definitions of

relative wind—the direction of movement of the atmosphere relative to an aircraft or an airfoil
angle of attack—the angle between a reference line on a lifting body (often the chord line of an airfoil) and the vector representing the relative motion between the lifting body and the fluid (i.e., air) through which it is moving
center of lift—the point at which the pitching moment coefficient for the airfoil does not vary with lift coefficient (i.e., angle of attack)
laminar flow—a flow regime characterized by high momentum diffusion and low momentum convection; the opposite of turbulent flow (laminar flow is smooth, while turbulent flow is rough)
dihedral—angle formed between the lateral axis and lower surface of the wing
aspect ratio—ratio of wing span to wing chord
angle of incidence—angle between longitudinal axis and the chord line of the wing
chord—straight line distance from leading edge to trailing edge.
