The wheels are on top, between and below the tracks.
The longest roller coaster in Asia is The Year of the Dragon. It has an 8,133 foot long track and is the longest coaster in the world.
Yes they can
The normal force at the bottom of a loop in a roller coaster track is greater than the force of gravity in order to keep the riders from falling off the track. This is because the normal force provides the necessary centripetal force to keep the riders moving in a circular path.
A roller-coaster moving down a track depicts an increase in potential energy. As the roller-coaster descends, it gains potential energy due to its height above the ground, which is converted to kinetic energy as it accelerates downwards.
Gravity.
It probably is because of the engine the pulls the coaster to the top
A roller coaster has more potential energy at the bottom. There are 2 types of energy, potential and kinetic. energy closer to a surface or floor is potential energy and objects in the middle of it all has kinetic energy.
The Fujiyama roller coaster opened in 1996. It was rated as one of the top 50 steel roller coasters in 2009. It has over a mile of track and is highly rated.
The normal force at the top of a loop in a roller coaster is responsible for providing the necessary centripetal force to keep the riders moving in a circular path without falling off the track. It acts perpendicular to the surface of the track to counteract the force of gravity and ensure the riders stay safely in their seats.
A duel track roller coaster.
To build potential energy, which is converted to kinetic energy upon descent. The higher up the roller coaster climbs, the more potential energy it builds, thus having more kinetic energy upon descent. Since there are no motors or engines, roller coasters are reliant on this back & forth transfer of energy.
Previous Answer => "Because of the law of inertia."Improved Answer => Well, yes I suppose, but it is not necessary based on that fact.Since roller coasters have a special three-wheel design that keeps coaster trains on the track NO MATTER WHAT, banking doesn't "keep the ride on the tracks". If anything, banking keeps the coaster safe (in terms of G's) and comfortable to actually be enjoyed versus being painful. A coaster and it's riders will follow the track no matter what, since again of the three-wheel design patented by John Miller in the 1920's AND the restraints on rides that keep people in. It is the G's that concern designers, not if the train will fall off.
