Designated by physics. Basic physical values, letters of meaning in physics

Physics yak science, yak vivchaє the laws of our Vsesvita, vikoristovu standard methodology of doslіdzhen i sing system odinits vimiru. it is accepted to mean N (Newton). What is the power to know and be? Let us vivchimo the price of food in more detail.

Isaac Newton is a typical English teaching of the 17th century, which has made unappreciated contributions in the development of exact mathematical sciences. It’s the very best of classical physics. You can describe the laws in the distance, how the majesty heavenly bodies, and other peasants, like a storm like a stream of wind, fall into the distance. One of the most important clues is the law of all-sacred labor and the three basic laws of mechanics, which describe the interaction of people in nature. As a result, they were able to bring the laws of grating, peace and quiet only to the science of Isaac Newton's science.

trochi theory

A physical value is named after the honored bul. Newton is one of Wimir strength. The very value of strength can be described as follows: "strength is the only one of the world of fashion between tilami, for the value that characterizes the steps of intensity or stress of bodies."

The magnitude of the force varies in newtons for a reason. We will give the blame to the three non-destructive "power" law, which are relevant and to our days. Let's vivchimo їkh on the butts.

first law

For a new reason, eat: "Chim є Newton?" і "Yakiy yogo physical zmist?"

The first to talk about those who, if only for the time being, do not conceal the need to flow in, then they will be known to be in peace. And as long as it used to be in Russia, then when there is a rise in the daytime, I’ll pour it into a new one, I’ll continue to develop my equal ruh in a straight line.

To realize that on the flat surface of the table lies a book with a singing mass. Having designated all actions on a new force, we can recognize that the power of the heavy is straight down, and (in the given table), is straight up the mountain. So, if they were offended, they were wrong to do one to one, then the value of the equal force was almost zero. According to the first Newton's law, the book itself is the reason why the book should rest.

other law

I will describe the interconnection between force, which is for tilo, and for the quickened, as soon as I will take away the applied force. Isaac Newton, with the formulation of the law, for the first time, the vicorist will keep the value of the mass and show the energy and energy in the world. Inertness is called building, for the power to take its own cob, to fix the underlying conditions.

Another law is often described by the offensive formula: F = a * m; de F - tse equal to all forces, applied to til, a - accelerated, to be rejected by til, and m - masa tila. The force in the kintsev pid-bag rotates in kg * m / s 2. Tsey viraz is taken to mean in newtons.

What is Newton in physics, which is the value of accelerated yake and how is it tied with power? The axis on the power supply is based on the formula of another law of mechanics. A slid of intelligence, which is the law of practicality only for quiet people, as they collapse with news that are less light. With the values of the properties close to the speed of light, there are also three laws, adapted by a special section of physics about the theory of validity.

Newton's third law

Tse, mabut, the very intelligence and simple law, which describe the interaction of two til. It’s worth talking about those who all tried to come up in pairs, so that it’s just like one with singing power, then and the other one’s only, in his heart, is also poured onto the face with equal strength.

The very formulation of the law is given to us by an offensive rank: "... together they are two-one-on-one, one on one, even if they are straightened in the opposite side."

Let's get rid of it, so also Newton. Physics has taken everything to look at specific features, that is, a spike of butts is guided to describe the laws of mechanics.

Water-flooded creatures for a quick swing, ribs or toads collapse near the water, or on the water itself, the plants in conjunction with her. Newton's third law is to say about those who, with the same style on the ground, are determined by the winners and prototypes; Whenever you go out, you can make a funnier, so that you can’t see how it’s stinking with your paws, pushing the water backward, and pouring it forward because of the drive’s drive.
Bigger wheel - yaskraviy butt prove Newton's third law. It's also a whitish wheel, I know everything melodiously. The process is simple and straightforward, with a wheel and a drum. They can be installed in the clitines, so that the home vikhovantsi nachebto bilek or decorative shchuriv could play. Vzaєmodiya two til, wheels and creatures, to produce before the offense til collapses. Moreover, if it’s fast, then the wheel is spinning with great speed, and if you are confident in its progress, then the wheel is turning more and more. It should be pointed out more than once that the idea is based on the opposite side.
Everything that collapses on our planet, collapses only the leaders of the Earth. You can be wonderful, protest when walking, the lecture must be done only in order to shave the ground, or be on the surface. And as we move forward, the earth will move us into the future.

But also Newton: is the unit of measure a physical quantity?

The very name of "Newton" can be described by the following rank: "the unit of strength". And why is the polyaga yogo physical zmist? Otzhe, vyhodyach from another Newton's law, the value is lost, as the force begins, which is built up in all in 1 second to change the speed of the weight of 1 kg per 1 m / s. Go, shho Newton - t. E. Vona can svіy straight. If the report is powerful to the subject, on the way of the door, then it is immediately put і directly to the ruch, yak, zgіdnogo with another law, if the same, as і straightforwardly.

As soon as the formulas are dictated, go, 1 Newton = 1 kg * m / s 2. When the new factories from mechanics are new, it is often necessary to translate Newton into the lowest value. For the sake of convenience, with the known quiet values, it is recommended to memorize the basic features, such as tying Newtones with the same units:

1 N = 10 5 dyne (Dina is a unit of vimir in the CGS system);
1 N = 0.1 kgf (kilogram-force is a unit of force in the MKGSS system);
1 N = 10 -3 stin (one unit in the MTS system, 1 stin for road power, which will be accelerated at 1 m / s 2, be it a weight of 1 ton).

The law of all sacred gravity

One of the most important clues about our planet turned upside down Newton's law of heaviness (read below). Zvychayno, and until the new boule try to solve the mystery of the heavy Earth. On the other hand, after letting it go, it’s not only the Earth that has an attractive force, but it’s also the very same thing to attract the Earth.

However, only Newton went into the distance to mathematically bring the interconnection of the force of the heavy and the laws of the planets. It’s not just the Earth that attracts objects to itself, but all the objects are magnetized one to one. Win viv the law of gravitation, which is to say, what if it was like this, including the heavenly light, would be attracted by force, so that it was expensive to add G (gravitational became) and mass of both til m 1 * m 2, distributed to R 2 ).

All the laws and formulas created by Newton made it possible to create a comprehensive mathematical model, as it is still happening in the past not only on the surface of the Earth, but far beyond the boundaries of our planet.

revision of one

In the event of a revision, there is a trace of memory about the standard ones, including those for the "Newtonian" units. For example, in zavdannya about cosmic objects, de masi bodies are great, even more often it is necessary to ask for great values before the smallest. Whenever a transmission is 5,000 N, then it will be recorded at a speed of 5 kN (kilonewtons). There are two types of single ones: multiples and parts. The axis itself is victorious from them: 10 2 N = 1 hectonewton (rN); 10 3 H = 1 kilonewtons (kN); 10 6 H = 1 megaNewton (MN) і 10 -2 H = 1 centiNewton (cN); 10 -3 H = 1 ml / Newton (mN); 10 -9 N = 1 nanoNewton (nN).

It is not a secret for anyone that there are special values for values in any science. To explain the meaning of physics, but science is not a fault in the plan for identifying quantities behind the addition of special signs. The main values, as well as the old ones, are rich in skin, and they have a symbol. Otzhe, the letters of the designation in the physics are reported in the data of the statistics.

Physics and basic physical quantities

The directors of the Aristotel started to get used to the word physics, as it was the first time to live the term, which at that time was used by the synonymic term of philosophy. The price is tied to the spirit of the object of vivchennya - the laws of Vsesvit, concretely - that, as there is a function. Yak vіdomo, in the XVI-XVII centuries the Persian revolution of science was brought about, the very founders of physics were seen in the independent science.

Mikhailo Vasilovich Lomonosov introduced the word physics to Russian language for the additional help of seeing the handler in the crossbar from the name of the first in Russia handler from physics.

Otzhe, physics є dissemination of natural knowledge, assignments to vivchennu zagalnyh laws of nature, as well as materia, її rukh and structures. There are not so many basic physical quantities, as you can look at the first glance - all 7:

dozhina,
masa,
hour,
the power of the struma,
temperature,
number of words,
the power of light.

Evidently, they have their own letters of meaning in physics. For example, the symbol is m for the mass and the symbol is T. for the temperature. Also, all values have their own unit of vimir: the strength of light has a candela (cd), and a few words have a single vimir є mol.

Current physical quantities

Outdated physical values are much higher, lower than the main ones. Їх nalichuєatsya 26, and often the actions of them are attributed to the main ones.

Otzhe, the area є obscenely from dozhini, obsyag - also from dozhini, shvidkist - from the hour, dozhini, and haunted, in its own devil, characterizes the shvidness of snake shvidkosti. The impulse rotates through the mass and the speed, the power - to the mass and acceleration, the mechanical robot to lay down from the strength and the energy, the energy is proportional to the mass. Strength, grip, strength, surface strength, line strength, amount of warmth, energy, electrical support, magnetic power, moment of inertia, moment of momentum, moment of strength - all the stinks lie behind. Frequency, kutova shvidk_st, kutova accelerated is wrapped in proportion to the hour, and the electric charge is directly depleted per hour. Kut і tіlesny kut є in old sizes from dozhini.

What letter is meant for springs in physics? A stress, like a scalar quantity, is denoted by the letter U. For the meaningfulness of the symbol, the letter v, for mechanical robotics - A, and for energy - E.

СІ: out-of-house views

The International System of Units (CI) is a system of physical units, which is based on the International System of Values, including the naming and value of physical values. Won was accepted by the General Conference from the world of that vag. The same system of regulation of the letter of meaning in physics, as well as its size and identity. For meaningful vikoristovuyutsya letters of the Latin alphabet, in some vypadkakh - walnuts. It is also possible as a designation of special symbols.

visnovok

Otzhe, in any scientific discipline є especially meaningful for a kind of size. Naturally, physics is not a blame. Lіternikh poznachen to finish the rich: strength, area, mass, acceleration, spontaneity, etc. Smells of their meaning. This is a special system, which is called the International System of One. Vvazhaєtsya, but the main ones cannot be mathematically vived from the others. Pochіdnі w values otrimuyut for additional multiplier and dіlennya from the main.
