There are currently over 6,500 active coasters in the world

Roller coasters are typically gravity- or inertia-powered trains that “coast” through steep drops, twists, and turns and are designed to offer thrills to amusement park visitors. The rides originated in 17th-century St. Petersburg with Russian ice slides—steep, ice-covered, wooden planks.

Roller coasters are believed to have originated in the 1600s with 70-foot wooden ice slides, typically enjoyed by the upper class. Over the past few centuries, the machinery developed into more daunting designs like the modern gigacoaster, which features a drop of 300 feet or more.
When a French traveler happened upon the 17th and 18th century Russian pastime of sledding down man-made hills, he brought the idea home and inspired others to modernize the mechanics. Adoration for coasters spread around Europe and eventually reached the US, where the scream machine would undergo major advancements.
Catherine the Great, the former empress of Russia, loved riding ice slides so much she added wheels to her sleigh to continue the fun during warmer seasons. This 18th century painting depicts her being led from her palace towards the icy slopes.
The Mauch Chunk Switchback Railway in the hills of Pennsylvania wasn’t initially intended to be a ride, but over time passengers and businessmen alike took advantage of the lovely tour through nature. The railway eventually reached over 100,000 riders in some years.
Despite their Russian origins, roller coasters are often associated with the US. This is in part thanks to a businessman and inventor named LaMarcus Thompson, who revolutionized the amusement industry in the US beginning with the Gravity Pleasure Switchback Railway at Coney Island. He is now known as the "father of the American roller coaster."
LaMarcus Thompson was an inventor and businessman who developed the first US amusement park ride in the 19th century and sparked a booming business. Customers spent a nickel to coast on wheeled benches over gentle hills, leaving Thompson with around $600 per day in profits.
There is only a certain amount of gravitational force that the body can handle before dealing with consequences like short-term vision loss or unconsciousness. Increased scientific understanding has largely reduced these impacts, with engineers combining periods of intense pressure with periods of relief.

Thanks to the incorporation of steel, rides have gotten increasingly versatile, daring, and smooth, performing loops and turns that are much more difficult to safely achieve with wood.

Inversions are when riders are flipped upside down on rides. Zero-g rolls involve turning 360 degrees with inversions, resulting in a temporary experience of zero g-force for passengers.
