Hi! Is it correct to say that work is a form of energy? At least that
is what the work-energy theorem seems to assert.

Yes it is. Yes, but what the mathemetical theorem spewers
don't seem to understand about work, is that most often
it is not workable energy.

Energy is the ability to do work. Naturally it has the same units.
If you lift a book onto a shelf then you have used energy to do
so, but you have also given the book the potential energy to
fall from the shelf and break your toe, thus doing work on your
foot. To do the work requires the book to convert its potential
energy to kinetic energy. Like money, energy is passed around
and can be converted to small change or accumulated - you
can add one more straw to the camel's back and break it.

It is strange that while, according to E = mc^2, energy is something
tangible, concrete, that has mass and or momentum, work, which has
neither mass nor momentum, and not even a physical presence, be also
called energy.

What does this mean. Work, Energy is a quantity whose unit is force X
distance.

Work seems to have all the characteristics of a spirit: it has no
mass, weight, momentum, or a physical body; it cannot be seen,
handled, or accelerated. It is very mysterious. Could it be a spirit?

Energy is a concept and well defined mathematically.

The Conservation of Energy is very fruitful in physics

Mass and thus energy is not defined, see...

Ask your bank manager when you deposit your pay cheque.
The numbers in your savings account seems to have all the
characteristics of a spirit: they has no mass, weight, momentum,
or a physical body; they can be seen, handled, multiplied by interest
rate and they can be added to or subtracted from if you do work or
hire someone to do work for you.They are very mysterious. Could
they be a bottle of vodka? (Mine can.)

I believe that work is done by forces that appear during energy
transformations. I think it is just an effect. I know of experiments
that show that the same force, applied through the same distance on
objects of different mass, can produce different amounts of kinetic
energy.
