A waterfall demonstrates both potential and kinetic energy. The water at the top of the waterfall has potential energy due to its height above ground, which is converted to kinetic energy as it falls down.
The same as any other falling object. When it is at the top, it has gravitational potential energy; as it falls, that's converted to kinetic energy.
If the object is placed at height, it has potential energy and when this object falls down, this potential energy is converted to kinetic (kinesis means movement) energy. If we have to lift object at height , we have to spend energy, witch is released during fall of the object. Example is when water comes down in hydroelectric power station potential energy is converted into kinetic energy. Witch is used to rotate wheel, creating electricity.
Kinetic Energy = 1/2 Mass * Velocity squared KE = (1/2)mV2 Your stream has mass and, if running, has velocity. So, this would be an example of generated kinetic energy.
That depends on whether the water is in motion. Water coming from a fire hose certainly packs a lot of kinetic energy. Water held in a reservoir behind a dam represents a lot of potential energy but no kinetic.
the energy in an object about to fall is potential energy then kinetic energy because when the object is not falling, it has potential energy but when it's actually falling, it has kinetic energy.

Usually by allowing an object to fall.
Kinetic
Yes, it does. Kinetic energy is energy in motion. If you have a waterfall, the energy within it is constantly being moved. If it were perhaps a waterfall that was frozen over, then it would not have kinetic energy; it would have potential energy. Relative to the pool at the bottom, the water at the top has potential energy until it reaches the edge. After it spills over, each kilogram of water loses 9.8 joules of potential energy and gains 9.8 joules of kinetic energy for every meter it falls. When it reaches the bottom, all of the potential energy it had at the top has been converted to kinetic energy.

Its a bad example, but some potential energy is involved. You convert chemical energy from the fuel to kinetic energy and heat energy. The kinetic energy drives you into the water. There the car sinks because of the height difference and gravity. This is a form of potential energy. A better example would be a person driving up and down a mountain. When driving up a mountain you store kinetic energy into potential energy. On the way down you regain the potential energy you stored, which results in a higher kinetic energy when driving down.
During one rise and fall of the ball, the gravitational potential energy and kinetic energy are equal two times: at the highest point (when all energy is potential) and at the lowest point (when all energy is kinetic).
