Explain why the water at the foot of the waterfall is at different temperature from that at the top?

When water reaches the ground, its gravitational potential energy is converted into kinetic energy. A part of its kinetic energy is converted into heat on reaching the surface. This causes a rise in temperature of water. So, the water at the foot of the waterfall is at a higher temperature as compared to the water at the top of the waterfall.

why is force attractive when the separation between body and force increases and potential increases and vice versa? why is force repulsive when separation between body and force increases and potential decreases? if PE/force is negative why attraction and if PE/force is positive why there is repulsion? pls explain and prove the above points with suitable examples.
