If on top of the roller coster is moving it is kinectic if not potential
It depends on the roller coaster's height,speed,and location. :p
The World's most strongest, the fastest and the scariest roller coasters is the hypersonic roller coaster, the underwater roller coaster, the twister roller coaster, the dinosaur roller coaster and the volcano roller coaster.
74mph is the top speed
The roller coaster does not have kinetic energy at the top of the hill
It probably is because of the engine the pulls the coaster to the top
15 mph
They don't.
The potential energy is highest at the top of the first hill or peak of the roller coaster because it is at its maximum height above the ground. As the roller coaster descends, potential energy is converted into kinetic energy as the car gains speed.
The voyage roller coasters top speed is 67.4mph
The Fujiyama roller coaster opened in 1996. It was rated as one of the top 50 steel roller coasters in 2009. It has over a mile of track and is highly rated.
2,800 feet
The "average", vanilla roller coaster? Their top speed in descents is about 60 MPH. But some of the newer, death-wish "can-you-top-this" roller coasters? I wouldn't even hazard a guess!
