Gravitational potential energy.
The type of rock found at the top of a waterfall is called "Hard Rock"
Yes. If it was moving down the waterfall, it would would have kinetic energy.
From my understanding, yes. A waterfall is an example of potential gravitational energy and kinetic energy. The water is moving downstream at a fast pace (kinetic energy) and when reaching the drop off the water gains potential gravitational energy and drops towards the ground. Mechanical energy is a mix between Kinetic energy and any type of potential energy so yes, a waterfall is an example of Mechanical Energy.
It is an example of conversion of potential energy (at the top) into kinetic energy (at the bottom).
Dams
The water at the top of a waterfall has a great amount of potential energy.
The water at the bottom of the waterfall has lost some potential energy in falling the height of the fall, but it has gained kinetic energy because it is moving faster than it was at the top. For a free flowing waterfall, ie one which has not had water diverted into a hydro power turbine on the way from top to bottom, the total energy ie potential and kinetic must be the same at the bottom as at the top.
becomes kinetic energy
well first i think the water comes from the ocean
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.
hydro thermal or gravitational hydro where the water is evaporated and the steam pushes a turbine that creates energy. gravitational where the water falling hits and turns a turbine that creates energy
kinetic energy
