its all a matter of physics; energy, inertia ,and gravity.
how fast the roller coaster is going, how high the roller coaster is in the air,
gravity and momentum
That will depend on which part of the roller coaster you're talking about. The moving parts (the cars and the driving mechanisms etc) will be designed by a mechanical engineer. The structure of the roller coaster itself (the towers and trackway and the foundations on which it stands) will be designed by a civil engineer.
A clever and creative mechanical engineer is the person behind a great coaster.
They can be indoor or outdoor depending where they are building the amusement park.

Velocity is constant when the middle of the roller coaster is parallel with the ground (when the tangent of the curve the roller coaster is on has a slope of 0 at the center of mass of the roller coaster).
