Journey to the Moon
2
384,000 Km away from earth Diameter of 3,476 Km Density is 1/80 th of Earth Temperature range: 130°C to -180°C No atmosphere No liquid water, Ice at Poles

Maria: Dark flat areas due to lava flows Latin for seas. Galileo thought there were oceans Craters: Large round pits Caused by impact of meteoroids Chunks of rock or dust Highlands : Light-colored features that are mountains

Rocket : a device that expels gas in one direction to move the rocket in the other direction A rocket moves forward when gases shooting out the back of the rocket push it in the opposite direction 2 Forces: Action and Reaction
8
Law of Physics : For every force, or action, there is an equal and opposite force, or reaction. Thrust: Reaction force that propels a rocket forward Depends upon mass and speed of gases Greater the thrust the greater the velocity Action Force: Rocket pushes gases out Reaction Force: Gases push rocket forward
9
Escape Velocity: Velocity a rocket must reach to fly beyond a planet’s gravitational pull Orbital Velocity: The velocity a rocket must achieve to establish an orbit around Earth.
