once again, because summer is coming so soon I thought about going to seabreeze and riding the roller coasters. Roller coasters involve lots of physics such has gravity and mass. also on rides such as the screaming eagle which goes upside down, centripetal acceleration. because of the mass of the roller coaster and the mass of the people on it, the center seeking reaction occurs although it is not a true reaction. by applying a force towards the center of the circle, it moves in a circular pattern. Although the track maybe experiencing this force, the rider feels the center seeking force which then pushes them toward the outside of the car. if you know what the radius of the circle is and the velocity at which the ride is going, you will be able to find this center seeking force.
