Lesson 1: Flight Vocabulary

2. The amount of matter in an object.
6. The up or down movement of the nose of an aircraft.
8. A measure of the curvature of the airfoil.
9. The force of gravity that pulls objects downward.
10. The main body of an aircraft where wings and stabilizers are attached.
11. Resistance of the air against the forward movement of an airplane.
12. Small moving section at the rear of the stabilizer that helps to control the yawing motion of the aircraft.
14. The hinged part of the stabilizer on an aircraft that is used to deflet the tail of the plane up and down.
16. The force that attracts a body toward the center of the earth or any other physical body having mass.
19. The force that directly opposes the weight of an airplane and holds the airplane in the air.
20. A person who operates the flying controls of an aircraft.
21. For every action there is an equal and opposite reaction.
23. The part on an airplane that raises and lowers the wings causing an aircraft to roll.
24. To drive, or cause to move, forward.

1. The air or sky above a country that is considered to belong to that country.
3. The relationship among an obect's mass, acceleration, and an applied force (F=ma).
4. A push or pull on an object resulting from the object's interaction with another object.
5. A force applied to a body to propel it in a desired direction. This force moves an aircraft through the air.
7. The rate at which an object speeds up, slows down, or changes direction.
10. Objects at rest stay at rest and objects in motion stay in motion unless an external force is applied. Also known as the law of inertia.
13. The means by which aircraft and spacecraft are moved forward.
15. Up and down motion of the wings of an aircraft.
17. A streamlined surface designed in such a way that air flowing around it produces useful motion.
18. A gas or liquid that tends to take the shape of its container.
22. A side-to-side movement of the nose of the aircraft.
