Flight & Space

2. A vehicle, missile, or aircraft which obtains thrust by the reaction to the ejection of fast moving exhaust from within a rocket engine.
3. Branch of technology and industry concerned with aviation and space flight.
4. the cone-shaped nose of a rocket or aircraft.
5. For every action there is an equal and opposition reaction.
6. The force generated by the gravitational attraction of the earth on the airplane. Lift must be equal to weight in order to sustain flight.
8. As the speed of a fluid increases, its pressure decreases.
13. A rocket-launched spacecraft able to land like an unpowered aircraft, used for journeys between earth and craft orbiting the earth.
15. A force applied to a body to propel it in a desired direction. The force which moves an aircraft through the air.
16. The force that directly opposes the weight of an airplane and holds the airplane in the air.
18. Transferring of energy to an object, typically by pushing or pulling on that object.
19. The rate of change of velocity with respect to time.
20. To set or thrust in motion.

1. The means by which aircraft and spacecraft are moved forward. It is a combination of factors such as thrust (forward push), lift (upward push), drag (backward pull) and weight (downward pull).
2. An engine that produces thrust by expelling hot gases from a rear nozzle.
5. The relationship among an object’s mass (m), acceleration (a), and an applied force (F), is Force equals mass times acceleration (F= ma).
7. A fixed or adjustable vane or airfoil affixed longitudinally to an aerodynamically or ballistically designed body for stabilizing purposes.
9. helps to guide the rocket upward until it reaches enough velocity for the fins to engage.
10. 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.
11. also called the "O Ring" it holds the rocket engine inside the rocket.
12. A vector quantity that includes the speed and direction of an object.
14. assists in the safe recovery of the rocket.
17. A part or surface, such as a wing, propeller blade, or rudder, whose shape and orientation control stability, direction, lift, thrust, or propulsion.
