Flight and Space

3. The shape and features of land surfaces, including both natural and artificial physical features of an area
4. A side-to-side motion of the nose of the aircraft.
6. The main body of an aircraft.
8. The force that makes it difficult for one object to slide along the surface of another or to move through a liquid or gas.
9. The path of an object moving through space
13. The hinged part of the stabilizer on an aircraft that is used to deflect the tail of the plane up and down.
17. An aircraft similar to an airplane that has no engine
18. The height above the surface of the earth at which an object is located
20. The up or down motion of the nose of the aircraft.
21. Resistance of air against the forward movement of an airplane or rocket

1. The means by which aircraft and spacecraft are pushed forward
2. The curvature of the airfoil
5. The force of gravity that pulls objects downward. Not to be confused with mass, the amount of matter in an object
7. The force that directly opposes the weight of an aircraft and holds the aircraft in the air. In a rocket, lift and thrust are in the same direction
8. load The amount of available fuel loaded for a specific flight
10. Small moving section at the rear of the stabilizer that helps to control the yawing motion of the aircraft.
11. The rate at which an object speeds up, slows down, or changes direction
12. The force that attracts a body toward the center of the earth or toward any other physical body having mass.
14. The part on an airplane that raises and lowers the wings, causing the aircraft to roll.
15. An aircraft that uses four rotors to fly
16. Up and down motion of the wings of the aircraft.
19. A push or pull on an object
