Does reaction force only occur when it is in contact with another object?
And also if rollercoaster goes around in a circle, at the maxium height, why isn't there any reaction force (got this from a book). Personally, I think that rollercoaser have clamps attached between the path and the cubicle, so when it is at the top, shouldn't there be reaction force against weight point upward.
