Energy in language and science

This is a strong man.
He is an active man.
And He is capable.
He is energetic.
I am stronger for this work. And I can stand him. I have it
Energy for him or her.
This is work. I completed some of it yesterday, and I am continuing the rest
today .

All of these phrases contain the words: power. And the ability. And energy. And work.

These words have meanings that are understood in people's language, but their understanding is somewhat ambiguous. If you contemplated the meaning of power and ability, and the difference between them, you would not be able to exactly define this difference. Likewise, there is the difference between power and energy. You may say that they are the same thing, and your friend may say that they are different. Then work? any work ? The book carried you from one place to another. A woman's cooking is a job. And read a page from a work book.

Science can never contain any of this ambiguity in its words.

Besides this, the basis of science is analogy.
How do you measure things in science whose exact meaning is not determined?

For this reason, science differs from language in understanding the meaning of the words: power. Work. Ability . energy . And it became
These words are like this in science, idiomatically.

- Force:

In science, it is everything that affects a body and gives it a movement with a uniformly increasing speed. An example is an object falling from your hand. The force here is gravity, the Earth's gravity. It started from rest, so its speed was zero. But due to the force of gravity, its speed continued to increase every second of time by one, because that is how the Earth's gravity is. But the force exerted in dropping the body will be doubled if the body's mass is doubled. From these two meanings, the meaning of the increase in speed per second, and the mass of the body, they extracted the measure of force. It is the product of the body's mass multiplied by this speed.

Man, in his sense of a clear meaning of power, and an example of the purest thing it can have, even if it does not attain complete purity, has not found anything better than a power that God has deposited on its earth, that gravity. Everyone on its surface and whatever is on its surface are connected to it, and it does not go away, and it rotates on its axis. In space, they scattered.

This exploration of power and its clear meaning began when the need for it arose with the appearance of the first rays of the industrial era that we called the Industrial Revolution two or three centuries ago.

- Work:

In science, it is the effort exerted by a force in moving it

(It is the first, greatest, most comprehensive and hidden mover of this universe)

object a certain distance. The effort you expend by force in moving an object with two feet is, of course, double the effort you expend in moving it with one foot. The effort you expend in moving it 10 feet is five times what you expend in moving it two feet, and this effort is called work, and it is measured by the product of the force multiplied by the distance.

Power:

But this transfer, this (work), may be completed in seconds, or it may be completed in minutes, or more or less, so the speed of its completion has something to do with the matter. The power or unit by which it is measured is the amount of work done by a person or machine per second.

- Energy:

Energy remains, and it is the title of this word. It is usually applied to a characteristic of things that prepares them to accomplish (work). A person has energy, derived from his muscles.
The car has energy derived from burning its gasoline. The locomotive has energy derived from its steam.

The Earth's gravity contains energy, always ready to move a body from a high place to a low place, and in doing so it accomplishes work.
