## History 
The earliest types of carousels were most likely created by Arabians. The first carousels were made for adults to ride. Today carousels are made for children to ride. However, the carousel was first recognized as being a carousel in Europe. People most likely made the first carousels in the seventeenth century. However carousels were used in France, to practice a game they enjoyed playing. For this game, horsemen practiced playing a game on which they would ride wooden horses, horses that were carved out of wood. The wooden horses would be rotated by servants pulling at the rotating platform. This would be similar to the playground carousels. Or the horsemen would use real horses to rotate the platform. The carousel emerged as a ride when a toy dealer in France showed wooden horses on a rotating platform moved by human power or horsepower in the beginning of 18th century. Carousels became popular in America between 1880 and 1930. During this time, there were around 5000 carousels built.   Michael Dentzel, an American who immigrated from German and lived in Philadelphia, moved the rotary platform of his carousel using steam power or horsepower in 1814. Later, the carousels found in amusement parks had platforms moved by a machine. This concept is still being used today. It was invented in 1898 in America. Railroads were the first companies in America to purchase carousels for their customers' enjoyment. Other animals that have been used on carousels include "Mother Goose" and "Disney" characters. The "romance" side of the carousel animals is the side that faces the audience. On the romance side the animal had extra carvings and decorations. Most of the carousels in Europe and America turn counterclockwise. In Great Britain, carousels turn clockwise.

## The scientific principles 
A carousel is set up a little above the ground. The platform rotates under motor power in the middle and can move up and down. The number of seats resembling horses or other animals varies depending on the carousel but there are usually between 16 and 60. The horses on the platform are connected to a pole attached to both the floor and the ceiling of the ride. The velocity of a carousel’s rotation is about 5 rounds a minute. An average ride length is 2 to 3 minutes.
The speed of the ride is low in order to keep centrifugal force low because the faster it turns the more centrifugal force the ride will have. The axis in the middle has centripetal force, which is the opposite force of centrifugal force.
