When the roller coaster is at its highest position and is not moving then its potential energy is highest
at the top of the first hill, just before the first drop
Kinetic energy
It is gravitational potential energy.
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.
it would be the energy that is slowly increasing
The roller coaster does not have kinetic energy at the top of the hill
on a roller coaster what is the motor called that lifts you up on the first hill
there would be plenty of potential energy
When the roller coaster is at its highest position and is not moving then its potential energy is highest
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.
at the top of the first hill, just before the first drop
Kinetic energy
When you see a roller coaster you have probably noticed that the first hill of the roller is always the highest unless it has given potential energy. Potential energy is force or stored energy. This is happens because not all potential energy is converted into kinetic energy. Kinetic energy is the energy of motion.
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 bottom of the hill
It is easier to see this using a traditional roller coaster model. Most traditional Roller Coasters start by using a tow cable to pull them up a large "hill". When being pulled up this hill, mechanical energy is being used to give the roller coaster potential energy. At the top of this hill, the roller coaster has it's maximum potential energy. As it starts to go down another hill, it picks up speed. During the descent it is losing potential energy but at the same time gaining kinetic energy. The coaster will then lose kinetic energy but gain potential energy as it goes up the next hill. This cycle of gaining/losing potential and kinetic energy is the conservation of energy that you are looking for. Of course in a real roller coaster, some energy will be lost due to friction. This will come off as heat in the rails and the wheels of the roller coaster and it's structure.
