The critical value is not the height of the dam itself but the height, or "head" of water inlet above the turbine.
The higher the head the greater the pressure available, so provided it's also matched by sufficient flow the greater the power output.
To illustrate the first point, a 30m high dam will produce the same power output from a given generating set level with its base, as a 5m high dam whose turbo-alternator is 25m lower in altitude down-valley - neglecting flow losses by fristion in the longer pipe-line. It's still 30m head even though the dam wall is far lower.
Yes. The height of the water level above the turbine affects the water pressure, and therefore the amount of power that can be generated.
.potential energy equalls mgh, where m is mass of object, g is gravity, h is height of the object placed from the ground level. . When height increases potential energy also increases..
Increased mass and/or height increase potential energy.
Height directly affects gravitational potential energy, since this energy is equal to mgh (mass x gravity x height). Height does not affect kinetic energy, which depends on the speed, not on the height. Except indirectly - for example, if an object is falling down, its speed will usually increase.
The height can affect the amount a penny can hold. The shorter it is the less it can hold.
Mass, gravity, height.

The mass, height and the force of gravity at the location.

I would have gravitational potential energy, which is energy due to height.

The height you drop the ball from will affect the bounce height this is because as the drop height increases so does the bounce height it is all to do with energy transfers. Also the waste energy is the sound and heat energy hope this helps.
The coaster have a large amount of potential energy when it gain height, kinetic energy when it gain speed instead.
(Potential) energy is directly proportional to the release height.
It does - but the energy is so small (compared to the sun) that it takes crazy instruments to measure it.
