When the rock is high up but has not been dropped yet, it has a lot of gravitational potential energy because of its position. PE = (mass) x (G) x (height) After it is dropped, the lower it goes, the less potential energy it has. That bit of missing potential energy has become the kinetic energy that it now has on account of its speed of descent. KE = 1/2 (mass) x (speed)2
The Potential energy decreases as r increases.
It becomes kinetic energy. And as an object goes up against gravity, it gains potential energy and loses kinetic energy.
When a ball is dropped, it no longer has potential energy. Before it drops, you can calculate the potential energy (= mgh); to actually measure this, you would have to measure the force, and multiply that by the distance.
As a ball fall downwards, it's velocity continuously increases, therefore the kinetic energy increases. As the height from the ground level decreases, the potential energy decreases. Further, the total mechanical energy remains constant throughout the motion.
It's potential energy decreases.

When an object is dropped, its potential energy decreases. This is because potential energy is a result of an object's position or height above the ground. As the object falls, it loses height, which leads to a decrease in potential energy. At the same time, the object gains kinetic energy, which is the energy of motion.
It is tranferred/converted into kinetic energy (DECREASES)

As the apple falls, its potential energy decreases while its kinetic energy increases, until it lands, at which point it has maximum potential energy.
An object's potential energy doesn't depend on its speed. You can do anything you like with the object's speed, and it has no effect on potential energy.
The potential energy will have converted into some other kind of energy. For example, for an object in free fall, it converts to kinetic energy (the object moves faster); if there is some resistance, part of this energy will convert to heat.

Physically put, the electron has more energy the farther ( higher ) it is from the nucleus. Simple potential energy. PE = mgh
Yes. As the car goes down the hill, the potential energy decreases and the kinetic energy increases. However, not all of the potential energy becomes kinetic energy. Some of it is lost to heat and sound energy.
