• 9-9 Technology – the practical use of human knowledge to extend abilities, satisfy needs and wants, and solve problems.

    9-10 Engineer -applies scientific knowledge, mathematics, and ingenuity to develop technical solutions for problems facing mankind. 

    9-11 Obsolete technology - outdated computer hardware, software, or other technology that is no longer used, even if it is in working condition. A technology often becomes obsolete when replaced by newer or better technology.

    9-12 Invention- is a unique device, method, composition, process or discovery that did not exist previously.

    Innovation – An improvement on an existing invention.

    9-13 -Rocket- A missle, spacecraft, aircraft, or other vehicle that obtains thrust from a rocket engine. Rocket engines work by action and reaction. Rocket engines push rockets forward simply by throwing their exhaust backwards and extremely fast.

    9-16  System -  A combination of parts working together to accomplish a goal. 

    9-17 Aerodynamics - The study of how air flows around an object.

    9-18 Body Tube-  Also called the “airframe”. It is the main part of the rocket which all other parts are either attached to or contained within.

    9-19 Payload -The passengers, crew, instruments, explosive charge or equipment carried by an aircraft, spacecraft, or rocket.

    9-20 Propellant -is a chemical substance used in the production of energy or pressurized gas that is subsequently used to create movement of a fluid or to generate propulsion of a vehicle, projectile, or other object.

    9-23 Newton’s First Law - Objects in motion stay in motion and objects at rest stay at rest unless acted upon by an outside force (unbalanced force).

    9-24  Newton’s Second Law - Describes that the heavier an object, the more force you need to accelerate it.

    9-25  Propulsion -  Is a means of creating force leading to movement. A propulsion system has a source of mechanical power (some type of engine or motor, muscles), and some means of using this power to generate force, such as wheel and axles, propellers, a propulsive nozzle, wings, fins or legs.

    9-30 Aerospace Engineer-  Aerospace engineers develop new technologies for use in aviation, defense systems, and space exploration, often specializing in areas like structural design, guidance, navigation and control, instrumentation and communication, or production methods.

    10-2 Fins- Attached to the end of the rocket, they provide guidance after the rocket leaves the launch-pad.

    10-4  Sputnik - unmanned space missions launched by the Soviet Union in the late 1950s to demonstrate the viability of artificial satellites. Sputnik 1 was launched on October 4, 1957

    10-7 Robbert H. Goddard - The American father of modern rocketry, built and tested the world's first liquid-fuel rocket in 1926. His achievement is considered as significant as the Wright Brothers' first flight.

    10-9 Airfoil- a shape designed so that air flowing around it produces useful motion.

    10-10 - V2 Rocket -The “V” in V-2 stood for Vergeltungswaffe (vengeance weapon). Traveling at 3,500 miles per hour and packing a 2,200-pound warhead, the missile had a range of 200 miles. Developed in Nazi Germany under the leadership of Dr. Wernher von Braun.
