Aerodynamics: The interaction of air and the objects moving through it.

Airfoil: A surface shaped to lift or steer an aircraft

Thrust: A forward force that acts upon an object

Drag: Friction between a fluid (such as air) and an object moving through it.

Lift: An upward force created when air rushes over a shape (such as a wing)

Gravity: A natural force that attracts all objects to each other

Pitch: The up and down axis of flight, controlled by the elevators

Elevator: part of the horizontal stabilizer that is used to deflect the tail up and down, controlling the pitch

Roll: Tilting to the left or the right, controlled by the ailerons

Aileron: Hinged part of the wing used to control roll

Yaw: The sideways skidding axis of flight, controlled by the rudder

Rudder: Part of the vertical stabilizer used to deflect the tail to the left and right controlling the yaw.
Dihedral: The angle between the wing and the horizontal (wing ends on an upward angle), Help lateral stabilization
