Potential energy to kinetic energy
Chemical energy
Any time something falls, rolls, or slides down, gravitational potential energy is converted into kinetic energy.
Whenever anything falls down, rolls downward, etc., gravitational potential energy will be converted into kinetic energy.
The situation is similar as when an object falls. Potential energy is converted to kinetic energy (including rotational energy in this case); part of that kinetic energy is converted to heat energy.
As a car rolls down a hill, the motion and gravitational potential energy(GPE) will be equal when the kinetic energy is equal to the potential energy.

When rolling down, potential energy is converted into kinetic energy. If there is no friction, this means the skater moves faster and faster. If there is energy (the usual situation), part of this movement energy (kinetic energy) will be converted into heat.
It is conserved. The potential energy of the ball sitting at the top of the hill is converted into kinetic energy of the rolling ball.
Assuming it just rolls down a slope, without the engines working: gravitational potential energy will be converted to kinetic energy. The kinetic energy will eventually be converted to heat energy.
