If the satellite goes too slow:
- It will crash into it's surrounding things it's orbiting.
- It would not go forward enough due to pull of gravity.
- Gravity will pull it back to Earth.
- The satellite could be knocked or moved closer or farther from the object it is orbiting.
If the satellite goes too fast:
- It will eventually fly away.
- It can go forward soo fast.
- It would go too fastly that gravity can't retain in an orbit.
- The satellite's inertia would carry it off into space.
