      It’s called the centrifugal force. The rollercoaster is going really quick so it’s pushed against the tracks even though its upside down. This force is so great, it counteracts gravity so the roller coaster doesn’t fall off. When you’re on a rollercoaster you’ll feel these forces pulling you down, or pushing you from side to side.
      Some roller coasters may be fixed on to the track as well for safety 🙂
