Thermal energy is heat. Heat is associated with motion (like a roller coaster) because of friction. Friction slows down the speed of an object and changes some of its kinetic energy into heat.

A roller coaster increases kinetic energy when it is going downhill, as gravity is pulling it down and accelerating it. The potential energy is converted into kinetic energy as the roller coaster gains speed.
When the roller coaster is at its highest position and is not moving then its potential energy is highest
When the roller coaster is at its highest position and is not moving then its potential energy is highest
Thermal energy plays a role in a roller coaster primarily through the conversion of potential energy to kinetic energy as the coaster descends. When the coaster climbs to the highest point, gravitational potential energy is at its maximum, and as it descends, this energy converts to kinetic energy, increasing speed. Additionally, friction between the coaster and the tracks generates thermal energy, which can slightly reduce the overall energy efficiency of the ride. This heat can also affect the materials of the coaster over time, influencing maintenance and safety considerations.
In addition to kinetic, potential, and mechanical energy, a roller coaster also involves thermal energy due to friction between the coaster and the track. As the coaster moves, some energy is converted into sound energy, which is produced by the interactions of the coaster with the air and track. Additionally, gravitational energy plays a significant role in the coaster's motion, particularly during ascents and descents.

No, the roller coaster is not the only example of a closed energy system.
The cars of a roller coaster reach their maximum kinetic energy when at the bottom of their path.
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 model uses less energy than the real one does.
