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
|
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
|
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. |

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

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.
