| Aerodynamics | The study of the forces acting on an object as it moves through the air. |
| Basic Plane Parts | The wings, the fuselage, the tail, the landing gear, and the engine. |
| Landing Gear | Also called the undercarriage, it supports the weight of the plane. It can be either Fixed or Retractable. |
| Ailerons | The hinged sections along the back part of the wing near the tips. They help the plane stay stable, bank, or turn. |
| Flaps | The hinged sections along the back part of the wing near the body of the plane. They help the plane lift during take-off and drag during landing. |
| Fuselage | The body of the plane from the nose to the tail. |
| Tail | Located at the rear part of the plane, it helps guide the plane and keeps it balanced in flight. |
| Basic Tail Parts | The verticle fin, the rudder, the horizontal stabilizer, and the elevator. |
| Fin | It stands upright, does not move, and keeps the plane from swinging side to side. |
| Rudder | The hinged piece on the back of the fin that moves from side to side. It helps control the plane during a turn. |
| Stabilizer | A small wing-like part in the tail which prevents the tail from bobbing around and helps maintain steady altitude. |
| Elevator | The hinged piece on the rear edge of the stabilizer which raises or lowers the plane's nose. |
| Four Basic Forces of Flight | Gravity, lift, drag, and thrust. |
| Gravity | The natural force that pulls the plane toward the ground. |
| Lift | The force, created by the wing as it moves through the air, that pushes the plane upward. |
| Thrust | The force, caused by the plane's propeller or jet engines, that moves the plane forward. |
| Drag | The natural force of air that resists the plane's forward movement. |
| Basic Plane Movements | Pitch, roll, and yaw. |
| Pitch | The movement of the plane's nose up or down. |
| Roll | The spinning movement of the plane. |
| Yaw | The sideways movement of the plane while flying at the same altitude. |
| What controls the pitch of the plane? | The elevator controls this to help with take-off and landing. |
| What controls roll? | The ailerons control this spinning of the plane. |
| What controls yaw? | The rudder controls this sideways movement of the plane. |
| What happened on December 17, 1903 at Kitty Hawk, North Carolina? | The Wright brothers successfully fly an engine driven plane. |
