Flight and Space Vocabulary

2. the clockwise or counterclockwise rotating motion of an aircraft.
4. a controlling surface on an aircraft's tail that regulates yaw.
5. resistance of the air against the forward movement of an airplane.
8. The major horizontal surface on an airplane that provides lift.
12. Objects at rest stay at rest and objects in motion stay in motion unless an external force is applied. It is known as the law of inertia.
15. the central body of an aircraft where wings and stabilizers are attached.
18. the means by which aircraft and spacecraft are moved forward.
19. relates to speed five or more times that of sound in air.
21. the quatity of matter, which a material contains.
22. a force applied to a body to propel it in a desired direction. The force which moves an aircraft through the air.
23. the force that attracts a body toward the center of the earth or toward any other phyhsical body having mass
25. as the speed of a fluid increases, it's pressure decreases.
27. the relationship among an object's mass, acceleration, and an applied force.

1. a gas or liquid that tends to take the shape of its container.
3. an airfoil (usually at the back of an airplane that resists up and down changes in motion.
6. a vertically oriented airfoil at the back of an airplane that resists left and right movements.
7. The force that directly opposes the weight of an airplane and holds the airplane in the air.
9. For every action there is an equal and opposite reaction.
10. 760 mph. When a plane travels faster than this speed it is breaking the sound barrier.
11. an airplane with no attached source of thrust.
13. The force generated by the gravitational attraction of the earth on the airplane.
14. the rate of change of velocity with respect to time.
16. an engine that produces thrust by expelling hot gases from a rear nozzle.
17. Transferring of energy to an object, typically by pushing or pulling on that object.
20. the controlling surface that regulates an aircraft's pitch.
24. a side-to-side motion of the nose of the aircraft.
26. the up or down movement of an aircraft.
