## What happens if a satellite orbits too fast?

Explaining orbits If the satellite is moving too quickly then the gravitational attraction between the Earth and the satellite is too weak to keep it in orbit. If this is the case, the satellite will move off into space. This occurs at speeds around or above 11,200 metres per second (m/s).

## What happens as a spacecraft speeds up?

As the spacecraft moves down, the potential energy decreases. It turns out the potential energy decreases more than energy needed to orbit. The K curve gets bigger, but the total energy curve gets smaller. So, you speed up but you have to fire your rockets backwards.

## What happens if a spacecraft in orbit slows down too much?

If the satellite slows down it would crash into the object it is orbiting. The satellite could be knocked or moved closer or farther from the object it is orbiting. If it moved closer, gravity would pull more strongly, if it moved farther, gravity would have less of a pull.

## Can you stay still in space?

Our universe works similarly, but we’re embedded on a three-dimensional space instead of a two-dimensional one. There is no ‘still’ that is not relative to some other object. So yes, you can be still with respect to one object, but you’ll be moving with respect to every other object.
