1. The problem statement, all variables, and given/known data
Satellites orbiting the Earth are often put into orbit at different heights around the planet. What affect will this have on the motion of the satellite and how exactly would the motion of a very high orbit satellite differ from one neared to the Earth?

2. Relevant equations
None

3. The attempt at a solution
The closer the satellite to the Earth the stronger the force of Earth's Gravitational Field. If the gravitational force is greater than the Forward Motion Force wouldn't the satellite slowly get closer to the Earth and then Crash?

Thanks for any help provided

Are you sure that you don't have any "Relevant Equations"? I don't know what has been covered in your class, but there are equations for the velocity of an orbit.

The thing is that my school does not teach you Astronomy. They give you this massive booklet with 50 questions you need to answer and it has to be handed in on the first lesson of the year...

It is meant to refine your research skills or something like that.. I don't really understand what they were thinking when they did that...

No textbook? If research techniques are to be learned, then you should start by trying Google to see if you can get an equation for orbital velocity.

I'll just tell my teacher that out of the 50 questions this one I did not understand.

That link should tell you all you need to know to fill in the "Relevant Equations" field and answer the question.
