  • An object that has an elliptical path

Question 2

Question
What of the following could be thought of a satellites?
Answer
  • The moon
  • Earth
  • The Sun
  • Venus

Question 3

Question
What is a geostationary orbit?
Answer
  • An orbit of a satellite that moves around the equator
  • An orbit of a satellite that moves from one pole to another
  • An orbit of a satellite that is fixed on one place above the equator
  • An orbit of the moon around the Earth

Question 4

Question
Why does a satellite in geostationary orbit seem to be fixed in one place?
Answer
  • It is not moving
  • Its speed matches the turning speed of the Earth
  • It is an optical illusion
  • They stay at the same height (altitude)

Question 5

Question
What is a Polar orbit?
Answer
  • An orbit that moves along the equator
  • An orbit that moves around the North pole
  • An orbit that moves around the South pole
  • An orbit that moves from one pole to another

Question 6

Question
What is an advantage of a satellite in geostationary orbit?
Answer
  • You can have your TV satellite dish fixed in one place and don't have to move it
  • You can map the whole of the Earth in one rotation
  • You can monitor the weather over all of the world
  • They take only 24 hours to make each orbit

Question 7

Question
What is an advantage of a satellite in a Polar orbit?
Answer
  • You can scan the whole of the Earth's surface in one orbit
  • They rotate at the same speed of the Earth
  • They orbit the equator
  • They can be used for TV and radio communications

Question 8

Question
What uses can you have for satellites?
Answer
  • Communications
  • GPS (Global positioning satellites)
  • Spying
  • Mapping the Earth
  • The Internet

Question 9

Question
Satellites at a lower orbit move slower than satellites in a higher orbit
Answer
  • True
  • False

Question 10

Question
The higher the orbit, the longer time it will take a satellite to rotate around the Earth
Answer
  • True
  • False

Question 11

Question
Why does a lower orbit satellite move faster than a higher orbit satellite?
Answer
  • The altitude is less
  • There is a greater gravitational pull
  • There is more friction to overcome
  • The weight of the satellite is more
