kinetic energy
A rock at the edge of a cliff has potential energy. This energy may be converted to kinetic energy by the force of gravity if it falls off the cliff.
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.
If it's not moving it doesn't have any energy
A rock that is sitting on top of a cliff has what is called potential energy.

Attrition.

No. That is a rock fall.
Weathering makes rocks at the top of a cliff suddenly fall.
slump

It falls and break
when an apple falls out of a tree, a person jumps off a building and many more
The higher rock has more potential energy
