iT DEPENDS IF YOU ARE TURNED ON OR NOT...
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.
The cars of a roller coaster reach their maximum kinetic energy when at the bottom of their path.
On a pendulum, the greatest potential energy is at the highest point of the swing on either side, and the greatest kinetic energy is at the bottom of the swing. On a roller coaster, the greatest potential energy is at the top of a hill, and the greatest kinetic energy is at the bottom of the hill.
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.
Potential energy is used when going up hill on a roller coaster. When it starts gong down the potential energy is converted to kinetic energy.
Kinetic energy comes from movement. If the roller coaster is moving at the top of the hill, it has kinetic energy. if the rollercoaster isn't moving then it has potential energy.
The roller coaster does not have kinetic energy at the top of the hill
kinetic
A corkscrew on a roller coaster would have kinetic energy as it moves through the track, turning potential energy (stored energy due to its height) into kinetic energy (energy of motion).
If its moving it has kinetic energy
A roller coaster has more potential energy at the bottom. There are 2 types of energy, potential and kinetic. energy closer to a surface or floor is potential energy and objects in the middle of it all has kinetic energy.
Mechanical energy is used on the chains that pull the roller coaster cars up the tallest incline, which is typically located at the start of the track. Mechanical energy is also used in the braking system that slows the cars to a stop at the end of the track.
