Across
- 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.
Down
- 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.
