What kind of energy does a waterfall exhibits?
Basically the same as any falling object. When the water is at the top, it has mainly gravitational potential energy (it will also have some kinetic, i.e. movement, energy). When it gets to the bottom, the potential energy will have been converted into kinetic energy, i.e., the water moves much faster.

Gravitational potential energy.

what kind of energy does afloating balloon have
Why do dams have a broader base?
There are two main reasons for a dam's broad-base design, and both are explained by the fact that all materials have limited strengths. The only practical way to increase strength is by adding material. The first idea is that a dam has to support its own weight. The heavier a dam gets, the more material is needed at the base to support itself. Hence very large dams have enormous bases. The second idea is that the dam has to also support water behind it. The top of the dam is thinner because it does not have to support too much water; only the surface of the water needs support. But as the water gets deeper, the dam has to support all that water above , and then its own weight. At the bottom, the dam has to support all the water and its own weight. This means that as you get lower, the dam has to get stronger. And as mentioned above, the only practical way to do so is to add material.
What form energy does the water in a water fall have?
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.
What is potintiel energy?
Potential energy is "stored energy" because of its position in space. For example, a car parked at the top of a hill, or the water behind a dam.
Why do dams need to be thicker on the bottom and thiner at the top?
because the water pressure on the damn is much higher on the bottom of it than the top.
Why are dams over rivers are made broader at bottom than at the top?
The pressure of the water (the weight) is greater at the bottom, due to the depth of the water. As the pressure is less near the top, the top of the dam wall doesn't need to be as thick as the bottom of the dam wall.
Why the base of the dam is made wider?
The pressure of the water against the top of the dam wall, is much less than the pressure exerted against the bottom of the dam wall. The width of a dam wall increases to compensate for the increased water pressures at the lower level.
Can potential energy be turned into work?
Of course. That's exactly what happens when the water at the top of the lake behind the dam pours down through the pipes and turns millstones or generators on the way down.
In a dam a hole is formed through which water flows. why will it be more difficult to plug the leak if the hole is located at the bottom of the dam than if it is at the top?
Because the pressure of the water is a lot stronger at the bottom of the water and a lot less strong closer to the surface of the water
What is the Kinetic Energy of 5kg of water just before it hits the turbin from the a dam 30m high?
(This assumes that the water is fallingverticallywith nohorizontalmovement.) The speed of the water at the top of the dam is 0. We can find the speed of the water at the bottom of the dam with the equation v2= v02+ 2ax, where v0is 0, a is 9.81 m/s2(accelerationdue to gravity), and x is 30.v2= 2(9.81)(30) = 588.6v = 24.26 m/sThekineticenergyis then (1/2)mv2= (1/2)(5)(24.26)2which is about 1472 Joules.

Waterfall is what kind of energy?
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
What kind of energy would a skier have if standing at the top of a hill?
Gravitational potential energy.
Why dams must be constructed so that they are much thicker at the bottom than the top?
Because the water pressure at the bottom of the dam is much more than the top.
Why is the base of a dam thinner then the wall?
The pressure against the dam wall increases at the lower levels than nearer the surface. So I expect the foot of the dam wall to be thicker at the bottom than at the top.
