Roller supports are free to rotate and translate along the surface upon which the roller rests. The surface can be horizontal, vertical, or sloped at any angle. The resulting reaction force is always a single force that is perpendicular to, and away from, the surface. Roller supports are commonly located at one end of long bridges. This allows the bridge structure to expand and contract with temperature changes. The expansion forces could fracture the supports at the banks if the bridge structure was "locked" in place. Roller supports can also take the form of rubber bearings, rockers, or a set of gears which are designed to allow a limited amount of lateral movement.

How does newtons third law relate to a roller coaster?
Whenever one object exerts a force on a second object the second object exerts an equal and opposite force on the first. Since a roller coaster is on a ramp, the ramp has to support the (apparently larger) weight of the roller coaster, especially when it turns it back up against gravity at the bottom of each incline. The rollers on each car also prevent the cars from leaving the track on turns, by exerting a controlling force using the sides and upper half of the track.
Where is potential energy the highest on a roller coaster?
When the roller coaster is at its highest position and is not moving then its potential energy is highest

What is the difference between simple support and pin-joint support?
We tend to use them to mean the same thing. In two dimensions, a simple support is one that allows rotation. A pin joint support is a simple support that allows rotation but not translation. A roller joint support is a simple support that allows rotation and translation.
