|The Simple English Wiktionary has a definition for: roller coaster.|
The roller coaster (some people say the simple form coaster) is a kind of amusement ride. A roller coaster is like a train. It has a number of carriages that travel on a set of tracks. This track has hills and valleys (hills and valleys are parts of the track that go up and down), and sometimes has other features that will turn the train upside-down. The track can be made from wood or steel. Some roller coasters are made for children, so they do not travel very fast. Other roller coasters are made very tall and they travel very fast. Riders are generally restrained in place with a bar, a belt, or something similar.
Science[change | edit source]
A roller coaster works because of gravity, a force that pulls things down to the ground. Most roller coaster trains are pulled to the top of a hill with a machine. The train will slide down the track, which has a number of hills and valleys. As it slides down a hill, it will travel faster.
History[change | edit source]
In the United States, LaMarcus Adna Thompson patented the first roller coaster on January 20, 1865. He named his ride the "Switchback Railway," and workers pulled the carriage to the top of the track. The first modern steel roller coaster was the Matterhorn Bobsleds at Disneyland. It opened in 1959.
Types of roller coasters[change | edit source]
Today, there are two main types of roller coaster: Steel roller coaster and wooden roller coaster.
Steel roller coasters can be separated into many more types. In some roller coasters riders stand up or lie down. Some roller coasters sit riders below the rails or beside them instead of above the rails. Some roller coaters spin riders.
Until recently only steel roller coasters can turn riders upside down. Now both steel and wooden roller coasters can turn riders upside down.
