| Bernoulli's Principle | As the speed of a fluid increases, its pressure decreases. |
| Fuselage | The central body of an aircraft where wings and stabilizers are attached. |
| Aileron | The controlling surface that regulates an aircraft's roll. |
| Rocket Engine | An engine that produces thrust by expelling hot gases from a rear nozzle. |
| Dihedral Angle | The angle between an aircraft wing and a horizontal line. |
| Thrust | A force applied to a body to propel it in a desired direction. The force which moves an aircraft through the air. |
| Wing | The major horizontal surface on an airplane that provides lift. |
| Slats | Protrusions from the leading edge of a wing that, when combined with the flaps, results in a significant increase in lift. |
| Heavier Than Air | An aircraft of greater weight than the air displaced |
| Spoiler | Device used to destroy lift. Found on top of the wing and in varying sizes. |
| Acceleration | The rate of change of velocity with respect to time. |
| Airfoil | A part or surface, such as a wing, propeller blade, or rudder, whose shape and orientation control stability, direction, lift, thrust, or propulsion. |
| Aspect Ratio | The ratio between the wingspan and average chord of a wing. |
| Lift | The force that directly opposes the weight of an airplane and holds the airplane in the air. |
| Velocity | A vector quantity that includes the speed and direction of an object. |
| Turbine | A rotary engine that extracts energy from fluid turning blades. |
| Propulsion | The means by which aircraft and spacecraft are moved forward. It is a combination of factors such as thrust (forward push), lift (upward push), drag (backward pull) and weight (downward pull). |
| Flaps | Control surfaces attached to the trailing edge of the wing extending outward from the fuselage to the midpoint of each wing. Flaps can increase the lifting efficiency of the wing and decrease stall speed. |
| Drag | Resistance of the air (technically a fluid) against the forward movement of an airplane. |
| Hypersonic | Relates to speed five or more times that of sound in air. |
| Empennage | The tail assembly of an aircraft, including the horizontal and vertical stabilizers, elevators and rudder. |
| Camber | A measure of the curvature of the airfoil. |
| Angle of Attack | The acute angle between the direction of the relative wind and chord of an airfoil. |
| Weight | The force generated by the gravitational attraction of the earth on the airplane. Lift must be equal to weight in order to sustain flight. |
| Ramjet | An engine that can operate only when moving at high speed since it has no moving parts and no device for drawing in air. |
| Fluid | Air or liquid that tends to take the shape of its container |
| Elevator | The controlling surface that regulates an aircraft's pitch. |
| Roll | The clockwise or counterclockwise rotating motion of an aircraft. |
| Newton's 3rd Law | For every action, there is an equal and opposition reaction. |
| Pitch | The up or down movement of an aircraft. |
| Lighter Than Air | An aircraft of less weight that the air displaced. |
| Yaw | A side-to-side motion of the nose of the aircraft. |
| Rudder | A controlling surface on an aircraft's tail that regulates the yaw. |
| Gravity | The force that attracts a body toward the center fo teh earth or toward any other physical body having mass. |
| Horizontal Stabilizer | An airfoil (usually at the back of the airplane) that resists up and down changes in motion. |
| Trailing Edge | The rear edge of a wing. |
| Vertical Stabilizer | A vertically oriented airfoil at the back of an airplane that resists left and right movements. |
| Chord | The width of an airfoil or wing. |
| Glider | An airplane with no attached source of thrust. |
| Propeller | An airfoil mounted on a revolving shaft. It creates low pressure in front of it, thereby moving an aircraft forward because of the high pressure area behind the airfoil. |
| Newton's 2nd Law | The relationship among an object's mass (m), acceleration (a), and an applied force (F), is Force equals mass times acceleration (F=ma). |
| Leading Edge | The front, usually rounded, edge of an airplane wing or airfoil. |
| Force | Transferring of energy to an object, typically by pushing or pulling on that object |
| Newton's 1st Law | Objects at rest stay at rest and objects in motion stay in motion unless an external force is applied. it is known as the law of inertia. |
| Precise Input | A method of placing geometric entities at precise x and y coordinates on a plane. |
| Propellant | A chemical mixture that is burned to produce thrust. |
| Mach 1 | 760 MPH. When a plane travels faster than this speed, it is breaking the sound barrier. |
| Mass | The quantity of matter, which a material contains. |
