Potential energy😄😄😄
That is potential energy.
Gravitational potential energy is the type of energy stored in an object if it is raised in a gravitational field. A rock on top of a hill is a good example of this as it has a higher potential energy than a rock at the bottom of a hill.
The energy you put into something to make it move at a steady speed is called KINETIC ENERGY. It's the Kinetic Energy of a car that makes the brakes hot when you try to stop. The kinetic energy of the moving car becomes heat in the brakes of the stationary car which has lost its kinetic energy. There are two ways to get a car to the top of a hill. One is to start at the bottom and drive the car to the top and then stop again. This way, the engine pushed the car up the hill. The other way is to start a long way before the hill and build up speed along a flat road. Then you can turn off the engine and the car will coast to the top of the hill before it stops. This way, the engine put a lot of Kinetic Energy into the weight of the car before it got to the hill, and it was that Kinetic Energy which was used to get the car up the hill.

PE = mgh
kinetic energy
Movement is one example - Energy can be transferred from potential Energy (PE) to Kinetic Energy (KE). The classic example of this is the biker at the top of the hill. The biker has a lot of (PE) because he is at the top of the hill and that can be transferred to (KE) as soon as he starts going down the hill. The biker is now in motion and is now in the form of (KE). When he makes it to the bottom of the hill and is at a stop, he no longer has (PE) like he did when he was at the top of the mountain.
A rock on top of a hill has potential energy, not kinetic energy. If it starts rolling down the hill then the potential energy transforms to kinetic energy.
The roller coaster does not have kinetic energy at the top of the hill

Ultimately energy from the Sun in the form of fossil chemical energy. If the bus is at the top of a hill it also has potential energy and if it is moving it has kinetic energy - bot of these are still Sunlight energy.

Potential energy at the top and kinetic energy at the bottom.
When the rider is at the top of the hill, her potential energy is the greatest, and her kinetic energy is the least.
