Rockets & Satellites

Rockets & Satellites

1. Rockets Lift Off?

   • The force generated to lift a rocket/shuttle in space requires a great amount of force, and it uses the third law of motion
   • As they lift off, they burn fuel and push the exhaust gases downward at a high velocity
     • The gases then push upward on the rocket with an equal but opposite force
   • A rocket can rise into the air because the gases it expels with a downward action force exert an equal but opposite reaction force on the rocket

2. Satellites

   • Any object that orbits another object in space
   • Circular Motion
     • Centripetal Force
       • Any force that causes an object to move in a circular path
   • Artificial Satellites
     • Artificial Satellites are launched my people so that there can be things such as weather forecasts, text messaging or anything like that
   • Satellite Motion
     • Why don't satellites fall to the Earth because of Gravity?
       • Satellite's have a greater horizontal velocity than a ball would have, satellites all around earth
     • Satellites in orbit around Earth continuously fall toward Earth, but because Earth is curved they travel around it
