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

The cars of a roller coaster reach their maximum kinetic energy when at the bottom of their path.
No, the roller coaster is not the only example of a closed energy system.
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.
It depends on the roller coaster's height,speed,and location. :p
Friction between the roller coaster and the track surfaces causes some of the potential energy to be converted to thermal energy. As the roller coaster moves along the track, friction generates heat due to the resistance between the surfaces, leading to a transfer of energy in the form of heat. This conversion ultimately results in a loss of energy from the system.
