The World?s Fastest Roller Coaster
Known as the fastest roller coaster in the world, Formula Rossa accelerates its riders up to 149 miles per hour. Not only does this 92 second ride have a total length of 2200 meters and a vertical drop of 51.5 meters, but its passengers will experience almost 5.0Gs!
Amazing But True
- While roller coasters are all different from one another, they all follow the same basic principle. The system's potential energy is increased by gaining altitude. Then, gravity takes over, causing most of the potential energy to be converted into kinetic energy. Any of the leftover energy that has not been converted into kinetic energy by the end of the ride is energy lost due to friction.
- The energy at any given point along the ride is given as:
In the equation,

- Does the
Wextin the above equation serve to increase or decrease the speed at which the roller coaster can reach?
- How is the energy in the system distributed when one of the carts on the roller coaster goes through an upside down loop?
