A carousel
A **carousel**, also known as a **merry-go-round**, is a ride found in an amusement park or on a playground. It includes a circle-shaped rotating platform. A carousel found in an amusement park has seats made to look like objects such as automobiles, trains and animals. Animals that can be seen on a carousel might be horses, elephants, and swans. Carousels are often brightly decorated with lights, paintings, and animals around the outside. A carousel found in an amusement park often moves by machine power. A carousel is also a common toy on a child's playgrounds. Playground carousels are not powered by a machine. The children make the carousel spin by holding on to the handle bars that are attached to the rotating platform. The child will then run in a circle while holding on to the handle bars making the merry-go-round spin. The merry-go-round found on a playground will move faster or slower depending on how fast the child runs.

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.

The scientific principles

The actual path taken from someone trying to cross a carousel in a straight line
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.
