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.
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.
no
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.
there would be plenty of potential energy
The very first roller coaster was built in the 1400's in Russia.
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.
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.
at the top of the first hill, just before the first drop
you can find pictures of the first roller coaster ever built, in google.
