A rollar coaster stop at the top of the hill What can you infer about its kinetic energy?

The roller coaster does not have kinetic energy at the top of the hill


Where is potential energy the highest on a roller coaster?

When the roller coaster is at its highest position and is not moving then its potential energy is highest


What type of energy is slowly increasing as you are climbing to the top of the first hill on a roller coaster?

it would be the energy that is slowly increasing


In energy transformations when a roller coaster is at the top of the hill the kinetic energy is?

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.


What kind of energy keeps the roller coaster down the hill?

Kinetic energy


At which point will a roller coaster have the most stored energy?

at the bottom of the hill


How does the law of conservation-of energy relate to roller coasters?

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.


What energy is in a roller coaster?

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.


How the energy transfers determine the heights of the hills on a roller coaster?

the higher the hill the greater the energy transfers.


How does a roller coaster demonstrate potential and kinetic energy in action?

there is a lot of potential energy right before a roller coaster decreases in elevation. potential energy is at its highest on a roller coaster when the roller coaster is at its highest point. when it drops down it uses kinetic energy.


Which type of energy do you think always have at the top of the first hill on a roller coaster?

there would be plenty of potential energy


Where will you locate on a pendulum or roller coaster the greatest potential and greatest kinetic 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.
