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
74mph is the top speed
Intamin
It depends on the roller coaster's height,speed,and location. :p
420 Ft. Top Thrill Dragster. This coaster is currently the second tallest coaster in the world
15 mph
They don't.
If on top of the roller coster is moving it is kinectic if not potential
2,800 feet
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.
When a roller coaster reaches the top of a hill, it possesses gravitational potential energy due to its elevated position. This energy is at its maximum at the peak, as it has the potential to convert to kinetic energy as the coaster descends. As the coaster goes down, the potential energy decreases while the kinetic energy increases, allowing it to gain speed.
