Kinetic energy
The water above receives energy as it falls down the short waterfall. This energy was stored as potential energy in the gravitational field of the Earth and came out of storage as the water dropped. This energy which came out of the gravitational field ended up being expressed as the kinetic energy of the water. That is, the water gains kinetic energy as it drops. An ounce of water is going faster when it hits the bottom of the waterfall than it was when it went over the top of the waterfall.
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.
well when you swim you are moving witch has to do with konetic ,and patenchal is when u stop and store the energy soo the awnser is yess
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.

Kinetic energy
As water falls from the top of Niagara Falls, its gravitational potential energy is converted into kinetic energy. At the top, the water has maximum potential energy due to its height. As it descends, this potential energy decreases while its kinetic energy, associated with its speed, increases. By the time the water reaches the bottom, most of the potential energy has been transformed into kinetic energy, resulting in the rapid movement of the water.
The potential energy in the head of water is converted into kinetic energy in the turbine which converts the kinetic energy into electrical energy. Potential Energy of water -> Kinetic Energy -> Electrical Energy

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.
Kinetic
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.
When the water is heated, its molecules get additional kinetic energy due to it. This results in their increased velocity. As their kinetic energy gets increased, they try to overcome the force of attraction between themselves and eventually water changes into water vapour.
