What evidence best supports the idea that computers are helpful to roller coaster engineers?

The tug of gravity makes the ride fun. However, It can also make it dangerous when you go too fast. An automobile has a brake, but not a roller coaster. Before engineers build a new coaster, they make a computer model.

What evidence best supports the prediction that roller coasters will continue to be exciting in the future?

Coasters keep getting scarier and scarier. But more people want to ride them all the time. Hundreds of millions of people take a coaster ride each year. Why? Experts say some people look for excitement. "These people are attracted to thrills." says psychologist Frank Farley. So what's next for coasters? Well, Schilke wants to build a 510-foot-tall ride.
