It could also be a piano scale or a staircase.

The answer to this riddle is "a road" or "a path." These structures ascend hills and remain stationary while allowing vehicles and pedestrians to travel over them. Although they facilitate movement, they themselves do not move.
push it down a hill
You know what a hill is, right? You go up the hill and down the other side and you have gone over it. A dale is a small valley. You go down the dale and up the other side and you have gone over it.
It ran out of juice.

erosion
Gravity pulls it down and the weight of a car is less dense than a hill and therefore it goes down
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.
road
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
it is when soil moves slowley down or up hill very slowly.
The energy associated with sledding down a hill is primarily kinetic energy, which is the energy of motion. As the sled moves down the hill, the potential energy stored in the sled due to its position on the hill is converted into kinetic energy as it gains speed.

Gravity if you are coasting.
a hill is a steep road that has either grass or something else and goes both up and down
