Can anyone provide an explanation as to what the normal force is reacting to in the case when a jet is flying a loop-the-loop?? I understand for a rollercoaster that at the top of the loop the normal force is due to the track exerting a force back on to the rollercoaster cart, contributing to the centripetal force, but for a plane, where is the normal coming from?
Only thing I can imagine is that it has something to do with the inertia of the plane?? But then why would the normal act downwards at the top of the loop?
Cheers
