Is a roller coaster mechanical or electrical energy?
Most rollercoasters use an electric motor to move the cars up the track to the top of the first hill. As the cars move higher, they gain potential energy.

In roller coasters, the two forms of energy that are most important are gravitational potential energy and kinetic energy. Gravitational potential energy is the energy that an object has because of its height and is equal to the object's mass multiplied by its height multiplied by the gravitational constant (PE = mgh).
The train on a powered coaster usually picks up electricity from contacts in the rails (similar to an electric locomotive or a monorail) and may contain multiple motors. Some powered coasters are powered by a flexible cable connected to the train.
The potential energy of the roller coaster when it is at the top of a hill is converted into kinetic energy as the roller coaster speeds down the hill. As the roller coaster goes up another hill, it slows down. The kinetic energy is converted into potential energy.
While going down the hill, the roller coaster picks up more and more speed. The potential energy the cart had at the top of the hill transforms into kinetic energy at the bottom of the hill. Because you are moving so fast, you have a very high kinetic energy, and a very low potential energy.
The electromagnets are installed on the top, or the side of the track. A small gap is left between the two fins allowing for a third fin attached to the train to run in the middle, or either side of the electromagnets. For LIM systems, a current is directed to the pair of fins, therefore creating a magnetic field.
A roller coaster demonstrates kinetic energy and potential energy. A marble at the top of the track has potential energy. When the marble rolls down the track, the potential energy is transformed into kinetic energy. Real roller coasters use a motor to pull cars up a hill at the beginning of the ride.
When the cars are released from the chain and begin coasting down the hill, potential energy transforms into kinetic energy until they reach the bottom of the hill.As the cars ascend the next hill, some kinetic energy is transformed back into potential energy.
