Energy is the physical dimension which measures the capacity of a body or a physical system to do work
Physical force, of the nerves and the muscles, active power of the organism;
Dynamic force of the spirit, which expresses itself as the will and capacity to act.
In the philosophy of Aristotle, the crucial and actuating act or principle, in contrast to the determinable and potential matter or principal is potential.
In physics, the aptitude of the system to do a job, that is, that works in a process in which it produces work and which is commensurate with the work done,
Can present itself in different forms, convertible into one another, in relation to the processes and the phenomenon in which the system participates, and can be exchanged between different systems.

Have you ever asked yourself how much energy is needed to produce photographs?
We are not talking about electric energy ,that would be trivial, but of the energy burnt by the human body, from head to foot: K calorie
Thought and movement, brain, legs, arms…
In this case then there is in the midst sport, and so the calculations become more complicated.
Four photographs = 100,000 K calorie
The figure may be surprising, but let’s try to do some sums:
Photograph: well, from the initial set-up to four shoots, about 10,000
Two assistants for four shoots, around …25,000
Now the best part;
13 cyclists about twenty laps of the track…43,000
10 basketball players, a good match with extra time and stoppages, 7,000
4 volleyball players, innumerable dives and jumps, 1,500
15 athletes 3000 hurdles, true, they do not do laps of the track, but we have grilled them with sprint and jump 15,000
We add the trainers, and do not forget the account and ads of the agency that has followed them: 6,000
Adding up we arrive at approximately 107,500 K calorie from tables and calculations taken from internet.
Well, now what shall we do with this result?
With the value itself, I would say nothing, we are not obsessed with diets.
But I need one hundred and seven thousand five hundred K calories to thank everyone that has made these shots possible, as evidence of the energy that is needed to produce photographs, maybe a warning to those who think a simple click is all it takes.
Ah…I was forgetting, as always, Treccani online:
In technique, with reference to the mode of exploitation of energy and to the forms in which this is available for practical purposes, one currently talks of e.mechanics, e.thermals, e.electricity, e.water supply, etc., and one says source of e. any substance or process capable of making available to man a certain quantity of usable energy.
