Potential energy is gained as the roller coaster car goes up to the top of the first hill. This type of energy is due to the car's height above the ground and its potential to do work as it moves downhill.
never ? really the answer is that kinetic energy is changer to potential energy then when the laws of gravity and inertia come into play it is converted back into kinetic energy
No
The skier going up the hill gains potential energy due to its height increase, which is stored energy that can be released when the skier goes back down the hill. As the skier goes down the hill, the potential energy is converted into kinetic energy, which is the energy of motion.
An elevator, escalator?
