100

The system responsible for moving the rocket using engines and fuel

propulsion system

100

This country invented gunpowder rockets around 300 BCE

China

100

The force that pushes a rocket upward when gases are expelled downward

thrust

100

Objects that orbit Earth and provide communication, navigation, and weather data

satellites

100

The study of how air moves around objects

aerodynamics

200

This system includes sensors, computers, and communication equipment

guidance system

200

The scientist who published the laws of motion in 1687 that explain rocket movement

Isaac Newton

200

The law that states “for every action there is an equal and opposite reaction”

Newtons third law of motion

200

The usual lifespan range of satellites before they fall out of orbit

5-15 years

200

The force that slows a rocket due to air resistance

drag

300

The system that carries satellites, cargo, or spacecraft

payload system

300

: The first liquid-fueled rocket was launched in 1926 by this American physicist

Robert H goddard

300

Unlike airplanes, rockets can work in space because they carry this with them

oxygen

300

The power source most satellites use through large panels

solar energy

300

The force used to overcome gravity during takeoff and landing

lift

400

The rocket system that includes the nose cone, fins, frame, and skin

structural system

400

The rocket developed in 1942 that became the first to reach the edge of space

V-2 Rocket

400

what burns to create hot gasses that is then pushed out of the engine

fuel

400

The rocket stage satellites are attached to before deployment

the upper stage

400

The condition required for a spacecraft to move forward

thrust being greater then drag

500

The condition where a rocket’s center of pressure is behind its center of gravity

aerodynamic stability

500

The 1969 mission where humans first landed on the Moon

Apollo 11

500

The reason rockets do not need air to function in space

rockets carry their own fuel and oxidizer

500

Devices similar to satellites but that leave Earth’s orbit to explore other planets

space probes

500

The reason lift cannot be used in space

there is no air in space
