it would be the energy that is slowly increasing
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.
Energy. Potential energy is like stored energy: ready-to go. (a cart at the top of a roller coaster hill has a lot of potential energy) Kinetic energy is moving energy: in-motion. (when that cart goes speeding down the hill)
No it is not! The hill is moving in the opposite direction. You do not perceive the motion of the hill since it move sooo slowly... When the ball will stop with respect to the hill (for instance because of an obstacle rigidly connected to the hill) then the hill will stop too. And the potential energy of the ball will be transformed into heat and sound.
If a rock was about to fall off a hill, that would be potential energy. If that rock was sliding down the hill, that would be kinetic energy; it is actually moving.
It loses it's kinetic energy, the energy of motion. If it were logded against a rock on a hill, it has potential energy stored because of it's position on the hill.
Mechanical energy, if it is moving then it is kinetic mechanical energy. Or if it is at the top of a hill about to fall then it is potential mechanical energy.
If there is fuel in the tank then it has chemical energy in that fuel. If it is moving it has kinetic energy. If it is at the top of a hill then it has gravitational potential energy.
A moving car can have potential energy. It can be on a hill or a rise. This would give it gravitational potential energy. It can have gasoline, a battery with charge or both. This would give it chemical potential energy.
A ball going down a hill is energy in motion. You walking is also energy in motion. A car moving is another example of energy in motion.
The correct sentence with the correct preposition should read: "We climbed the hill slowly."
From a stand still, going down a hill on skates you are converting potential energy into kinetic energy.
