Explain what occurs to satellites when they travel too fast and too slow to keep in orbit

If a satellite were to be traveling too past it wouldn’t orbit the earth but travel farther away. and if the speed is too slow then the earth’s gravitational force would pull the satellite to the surface

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.
