Roller Coaster

A roller coaster is a type of amusement ride built on a form of elevated railroad track that carries passengers on a train through tight turns, steep slopes and other elements to produce unusual g-forces on the body. Most are designed to feel thrilling, though some aim instead for a gentler ride, and their trains usually consist of open cars coupled in a single line running a complete circuit that departs from and returns to the same loading station. Roller coasters are typically found in amusement parks worldwide, though some are also built in zoos.
