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.
If on top of the roller coster is moving it is kinectic if not potential
Potential energy is highest at the top of a roller coaster when the cart has the highest elevation. As the cart descends, potential energy is converted into kinetic energy, reaching its maximum at the bottom. The relationship between potential and kinetic energy is a transfer of energy, as one decreases while the other increases.
74mph is the top speed
When the roller coaster cart reaches the top of the second hill, its motion is characterized by a decrease in kinetic energy and an increase in potential energy compared to the bottom of the hill. At the peak, the cart momentarily slows down before descending, indicating a shift from upward motion to downward motion. This change reflects the conversion of potential energy back into kinetic energy as it descends. Additionally, the forces acting on the cart, such as gravity and inertia, influence its speed and acceleration differently at this point.
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
