The topic I have chosen for this project is Math in Roller coasters. The definition for a rollercoaster is; a steep, sharply curving elevated railway with small open passenger cars that is operated at high speeds as a ride, especially in an amusement park . The first roller coaster was made in 1885 in Russia. All roller coasters take a while to build, some could take up to two years and some could take up to only 10 months. Every roller coaster in the world is different.
