Techology

Roller coasters are made of wood or steel. Steel coasters are more popular, they can go faster, higher, and tend to have more inversions. Wood coasters offer a different type of thrill. Wood coasters are designed to shake and creek, the rider has fear that the ride will fail and it seems more dangerous (Roller Coasters). Most popular roller coasters have inversions, where the passengers flip upside down in the car, such as a loop or a twist. So how do you stay in your seat? The law of centripetal force is a physics concept that keeps you in your seat. When you spin fast in a circle the centripetal force pushes you to the outside of the circle which pushes you up into your seat when you are upside down. This happens when a bucket is filled with water and spun over your head, the water stays in the bottom of the bucket (Roller Coaster).
