No, the roller coaster is not the only example of a closed energy system.
A rollar coaster is a good example of electricitiy because on a roller coaster its easy to see where POTENTIAL and KINETIC energry fall.
Roller coaster's doesn't take the place of anything but it shows possession. Example: roller coaster's design
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.
An example of potential energy transforming into kinetic energy is when a roller coaster reaches the top of a hill where it has high potential energy due to its height. As the roller coaster descends the hill, the potential energy converts into kinetic energy as it gains speed.
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
yes kinetic energy is energy being released, for example going down a roller coaster
Energy is transferred from potential to kinetic on a roller coaster as the coaster descends from a higher elevation to a lower elevation. As the coaster moves downwards, gravitational potential energy is converted into kinetic energy. This energy transfer allows the coaster to gain speed and momentum.
