  2. Ailerons: Sections of the wings which can move up or down and control roll. • Air Pressure: The amount of force air exerts on an object. • Aircraft: Any weight-carrying structure designed to navigate through the air which can be supported either by its own buoyancy or the action of the air against its surfaces.

  3. Airfoil: An object designed to obtain maximum lift when moving through the air (wing, rudder). • Archimedes’ Principle: Any object placed in a fluid is pushed upward by a force equal to the weight of the fluid it displaces. • Attitude: The direction in which an airplane is pointing in relation to the earth’s surface (banking, pitching, yaw) or the relation of the wings and nose to the horizon.

  7. Pitch, Roll and Yaw http://www.youtube.com/watch?v=s9GJ_Tr3be8

  8. Basket: The container that transports people in a hot air balloon and is located below the silk. • Buoyancy: The ability of an object to float or rise when placed in a fluid.

  9. Control Surfaces: Small surfaces that can be moved to alter airflow and change an airplanes attitude. • Dihedral Angle: Upward slanting of wings away from the fuselage. • Drag: The resistance air exerts on a flying object.

  10. Types of Forces

  11. Elevator: The horizontal part of a plane’s stabilizer used to control pitch. • Envelope: The balloon which holds hot air in a hot air balloon. • Fuselage: The main body of the plane.

  12. Gliders: Aircraft that has no engines. • Gravity: The force of attraction that pulls objects earthwards. • Lift: The force opposed to gravity which lifts the airfoil.

  13. Pitch: Up or down attitude of the nose of the plane. • Rocket: Any devise propelled by the ejection of gases and air. • Roll: Rotation of the fuselage.

  14. Rudder: The hinged section of the tail of the airplane which helps the plane moves right or left; that is the yaw. • Shroud Lines: The connecting lines on a parachute. • Stability: The ability of an airplane to control pitch, roll, and yaw in order to maintain altitude after a disturbance.

  15. Terminal Velocity: The maximum velocity of a falling body. • Thrust: The force produced by an aircraft which pushes the plane upwards. • Vacuum: Where there is no air pressure.

  16. Weight: Relative heaviness. • Yaw: Left or right attitude of the nose of a plane.
