Where were we?
question: lake without salting out = force
1) in "
static", the "
strength"implies AND is defined as"
a mechanical action capable of imposing an acceleration".
So a static lake without salting out (and except infiltration) is a
mass gain, epicutout.
Hic wrote:a static mountain lake is potential energy
2) example of a simple mathematical formula (in static) calculation of the "
moment":
Force "F" (X)* "lever arm" (on the blades of a turbine).So no, if a lake is "
static", by definition there is no"
strength"who can speak, so no
"potential energy".

3) No, "
Potential force"only (and it takes a hydroelectric complex to turn that into"
Energy. ")

Hic wrote:magnet and lake are forces OK!
Always not...
we saw it for the lake.
By cons, magnets is insane.
They do not contain any particular energy. By cons, it takes a lot of energy to make ... And yes, there the dream takes a nasty blow and cost ...!
A magnet does not even contain any source of energy.
It just has a constant magnetic field around it.
So if it makes us believe what it makes us believe by being able to move metallic objects, it will take as much force applied to remove them from its attraction ...
What deludes the appreciation is that the only power of a magnet is to deform the ambient magnetic field. We see it in this experiment, just by sprinkling metallic particles (sensitive to its magnetic field) on it:

Once the particles are realigned, they are stable, static! There is therefore no energy, otherwise it would continue to panic!
By distorting the ambient magnetic field with its own magnetic field, the magnet realigns this field, but once the magnet is removed, the ambient magnetic field takes over!
Besides, a magnet has as much positive as negative field (the poles), it is enough to see the force which it is necessary to apply to the latter, to remove it from a metallic surface to which it would be stuck. CQFD, if there are forces they add up as much as they cancel out to return to equilibrium.
Some people think that we can extract magnets from energy, as we could extract from olive oil, it may be nice to believe it, but it is an urban myth.
