It is gravitational potential energy.
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.
Potential energy is used to get the roller coaster car up the first hill. The potential energy is converted to kinetic energy as the car goes down the hill. The potential energy is typically provided by a motor or chain lift system.
at the top of the first hill, just before the first drop
At the top of the first hill, PE is at its maximum, whereas KE is zero. When the train starts to fall down the first hill, PE decreases and KE increases. At the bottom of the hill, KE is at its maximum, and PE is zero.
Actually it is. The first law of thermodynamics tells us that you have to put energy into the roller coaster (in this case in the form of work) to get it to the top of the first hill; getting it to the top increases its potential energy. Once it starts moving down, most of that potential energy is converted to kinetic energy as it moves around the track. Over the course of its circuit of the track, energy is continuously converted back and forth between potential and kinetic energy - with some energy also being converted to heat through friction with the rails and with the air. Energy is conserved - thus we see the first law obeyed.

it would be the energy that is slowly increasing
the first roller coaster was made of wood.
The first roller coaster was at Coney Island in 1886.
To build potential energy, which is converted to kinetic energy upon descent. The higher up the roller coaster climbs, the more potential energy it builds, thus having more kinetic energy upon descent. Since there are no motors or engines, roller coasters are reliant on this back & forth transfer of energy.
no
there would be plenty of potential energy
The very first roller coaster was built in the 1400's in Russia.

The top of the first hill. This is where the coaster has its greatest amount of potential energy which is converted to kinetic energy as it moves along the track.

you can find pictures of the first roller coaster ever built, in google.
