Why are there loops in roller coasters?

They gain their energy at the beginning of the ride, when you are dragged up a hill then released to race towards the ground, and this energy needs to be maintained throughout the length of the ride. Circular loops allow this energy to be maintained because the loops are teardrop shaped rather than a perfect circle.

Officials in the US state of Wisconsin are investigating how eight people became trapped upside down on a roller coaster at a festival; some of them for more than three hours. The roller coaster's cars got stuck near the top of a loop around 1:30 pm Sunday at the Crandon International Offroad Raceway.

Elements have since evolved from simple corkscrews and vertical loops to more complex inversions such as Immelmann loops and cobra rolls. The Smiler at Alton Towers holds the world record for the number of inversions on a roller coaster with 14.

In 1846, Paris became home to the first Loop-the-Loop roller coaster, which included one small loop, 13 feet high. New York City's Coney Island, home to several amusement parks, followed with its own looping coaster in 1901.

The sensation roller coaster riders experience that makes them feel like they're being pushed into their seats as they go through a loop is commonly referred to as centrifugal force, although it isn't a force at all. It's the result of observing one's motion relative to the object in which one is traveling.

This places some limits on the design. For example, the coaster car can't go through a loop or over a hill that is taller than the initial hill because going higher would require more energy than it has available. If the track is too long, friction might eventually cause the coaster car to come to a complete stop.

A roller coaster ride comes to an end. Magnets on the train induce eddy currents in the braking fins, giving a smooth rise in braking force as the remaining kinetic energy is absorbed by the brakes and converted to thermal energy.

Kingda Ka is quite simply the tallest coaster in the world and fastest roller coaster in North America. Is that impressive enough to warrant royalty? You bet it is. This upside down U-shaped track bolts up 45 stories in the sky—that's 456 feet high!

The first tubular steel coaster was the Matterhorn Bobsleds at Disneyland, Anaheim, CA (1959). Knott's Berry Farm, Buena Park, CA, introduced the Corkscrew (1975), the first coaster to completely invert passengers.

It's the combination of lift hill and drop that are the scary parts for me. The lift hill builds anticipation so well, and then it's time for the hyper coaster level 90 degree descent, the first part of which occurs in total darkness.

Basic mathematical subjects such as calculus help determine the height needed to allow the car to get up the next hill, the maximum speed, and the angles of ascent and descent. These calculations also help make sure that the roller coaster is safe. No doubt about it--math keeps you on track.

In addition, when it opened, Son of Beast was the only wooden roller coaster to feature a vertical loop.
