* Gravitational Potential Energy (GPE):
- GPE increases as passengers are raised (moved further from the earth).
- GPE transforms back into KE as the wheel turns downward, accelerating the cars to their highest velocities at the bottom of the circle.
* Kinetic Energy (KE):
- After being released at the maximum height, cars accelerate by transforming GPE into KE
- Passengers reach maximum speed at the base of the circle with zero GPE
2. Electrical Energy
- Motor or engine powers the wheel to raise cars to the maximum GPE point(s)
