Rocket Systems
The system responsible for moving the rocket using engines and fuel
propulsion system
This country invented gunpowder rockets around 300 BCE
China
The force that pushes a rocket upward when gases are expelled downward
thrust
Objects that orbit Earth and provide communication, navigation, and weather data
satellites
The study of how air moves around objects
aerodynamics
This system includes sensors, computers, and communication equipment
guidance system
The scientist who published the laws of motion in 1687 that explain rocket movement
Isaac Newton
The law that states “for every action there is an equal and opposite reaction”
Newtons third law of motion
The usual lifespan range of satellites before they fall out of orbit
5-15 years
The force that slows a rocket due to air resistance
drag
The system that carries satellites, cargo, or spacecraft
payload system
: The first liquid-fueled rocket was launched in 1926 by this American physicist
Robert H goddard
Unlike airplanes, rockets can work in space because they carry this with them
oxygen
The power source most satellites use through large panels
solar energy
The force used to overcome gravity during takeoff and landing
lift
The rocket system that includes the nose cone, fins, frame, and skin
structural system
The rocket developed in 1942 that became the first to reach the edge of space
V-2 Rocket
what burns to create hot gasses that is then pushed out of the engine
fuel
The rocket stage satellites are attached to before deployment
the upper stage
The condition required for a spacecraft to move forward
thrust being greater then drag
The condition where a rocket’s center of pressure is behind its center of gravity
aerodynamic stability
The 1969 mission where humans first landed on the Moon
Apollo 11
The reason rockets do not need air to function in space
rockets carry their own fuel and oxidizer
Devices similar to satellites but that leave Earth’s orbit to explore other planets
space probes
The reason lift cannot be used in space
there is no air in space
