Roller Coasters
The World's most strongest, the fastest and the scariest roller coasters is the hypersonic roller coaster, the underwater roller coaster, the twister roller coaster, the dinosaur roller coaster and the volcano roller coaster.
The first roller coaster was actually a coal mining car in NY in 1895 that ran 18 miles down hill and would hit a 100 MPH. People came up to the hill where it was located and rode it down. Roller coasters became popular after WW1 and there were over 2,000 built in the United States in the early 1900's. In 1927 the Coney Island roller coaster opened. The early roller coasters were very dangerous and many people got hurt on them. They are called roller coasters because wheels are used for them to coast on a track. It is all done with gravity.
They are used for: Roller coasters, MRI scans, trains,refrigerators and etc.
The most used speed on roller coasters is 80 MPH, but a few go between 100-150.

Coal mines can range in depth from a few hundred feet to over a mile deep, depending on the location and mining method used. Underground coal mines are typically deeper than surface mines due to the nature of the coal deposits.
