| aerodynamics | study of forces acting on an object in motion through an atmosphere |
| aileron | used to control rolling |
| bank | turn made with one wing tip lower than the other |
| dihedral | uplift of wings to increase stability in the roll axis |
| elevator | control section of stabilizer used to change pitch |
| fin | fixed forward portion of vertical tail |
| fuselage | body of an airplane |
| glide | forward flight maintained only by the loss of altitude |
| motor stick | wooden strip used to support rubber motor of a model airplane |
| rudder | moving part of vertical tail used to control yaw |
| stall | complete loss of lift from too steep angle of attack |
| angle of attack | angle at which a wing strikes the air stream |
| airfoil | cross-section shape of a wing |
| lift | energy on top and bottom of wing that keeps the airplane up |
| thrust | pulling power of the propeller which pulls the plane forward |
| gravity | the force which acts to pull the plane down |
| drag | force which holds the airplane back |
| yaw | movement to the left or right |
| pitch | movement up or down |
| roll | bank (or lean) to the left or right |
