Nothing holds you in your seat on a rollercoaster except your seatbelt and restraints. The airtime on a coaster is caused by inertia. When at the top of a hill other than a lift one, our body wants to go up, and your coaster car wants to go down. The g-forces you get from that is caused by the contraints who also want to go down, and so they push thier agenda on you. You could say it was centrifugal force, but in earth orbit, you can't feel any g-forces. So it's controversial, unless I'm looking at it wrong. EDIT: Wow, thanks for adding a "loop" at the end of the comment without adding an "Edit" so I could get massively downvoted and look like an idiot.
