it decreases
gravity
It will decrease if the object moves upward; decrease if the object moves downward.
A moving fan is an example of kinetic energy, the energy of objects in motion. An example of potential energy would be a large rock at the edge of a cliff. If the rock falls off the cliff, its potenital energy (energy by virtue of its location), is converted to kinetic energy, energy of its motion, as it falls.
When an object falls, the potential energy gets converted to kinetic energy.
The longer it falls the more kinetic energy it gets while decreasing it's potential energy.

Yes, I believe so. As it gains upward momentum it is using thermal energy, and when it stops, and falls with gravity back to earth it is using kinetic energy. I think that's right.
The leaf does not fall straight down. It falls slowly because of air resistance. The air provides upward force. The upward force on the apple is negligible.

When an object falls, the potential energy gets converted to kinetic energy.
Free Fall
For example, when an object falls, its potential energy decreases, but its kinetic energy increases, i.e., it falls faster and faster.
The longer it falls the more kinetic energy it gets while decreasing it's potential energy.
As the clay falls it has kinetic energy
when the rock falls it gain kinetic energy when it falls.
