is water real
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.
Kinetic Energy is dynamic energy - energy that is causing action, and when it comes to water (and other liquids) this action is usually associated with the concept of "flowing" in a certain direction. Some examples are:Water falling from high altitude.Water streaming (flowing) in a river.On the other hand, Potential Energy is passive energy - for the time being it does nothing but it can cause actionat any time, given the required triggering. Examples are:Water in a reservoir restrained by a dam, which is totally quite but will flow once the dam gates are open.Water in a high water storage tank on a building's rooftop that is not flowing but will flow as soon as someone opens the tap.
A leaping frog is an example of kinetic energy. Before the jump, the frog contains potential energy. When it jumps, the potential energy converts to energy of motion, otherwise known as kinetic energy.
A lit match has both kinetic and potential energy. The potential energy is stored in the chemical bonds of the match head before it is lit, and the kinetic energy is released as heat and light energy when the match is ignited.
In a pendulum, potential energy is converted to kinetic energy as the bob swings down. At the bottom of the swing, the kinetic energy is at its peak while potential energy is at its lowest. As the pendulum swings back up, this kinetic energy is then converted back into potential energy before the process repeats.
The water has its maximum kinetic energy at the bottom of a waterfall where its velocity is highest. It has minimum gravitational energy at the top of the waterfall before it starts to fall, as it has not yet gained significant potential energy from being at a higher elevation.

you have to give it potential energy before it is kinetic

A roller coaster is a good example for a place to find both kinetic and potential energy. Before a drop, it has potential energy. At the end of a drop, it has kinetic energy. Half way through the drop, it has kinetic and potential energy at the same time.
Potential energy is energy that is soon to become kinetic energy.Say there is a rock on the top of a hill.That is potential energy.When it falls it becomes kinetic energy.
Potential and kinetic energy
A leaping frog is an example of kinetic energy. Before the jump, the frog contains potential energy. When it jumps, the potential energy converts to energy of motion, otherwise known as kinetic energy.
A lit match has both kinetic and potential energy. The potential energy is stored in the chemical bonds of the match head before it is lit, and the kinetic energy is released as heat and light energy when the match is ignited.
Kinetic energy depends on movement; potential energy only on the position (when there are forces that act on an object).
Kinetic and potential.
In a pendulum, potential energy is converted to kinetic energy as the bob swings down. At the bottom of the swing, the kinetic energy is at its peak while potential energy is at its lowest. As the pendulum swings back up, this kinetic energy is then converted back into potential energy before the process repeats.
