What to do n. Unit of force: Newton. The strength of the normal reaction of support
All the sounds in life live the word strength in the individual characteristics, seemingly people are stronger than women, a tractor is stronger than a car, a lion is stronger than an antelope.
Strength in physical form begins as the world of change of shvidkosty tila, as it is seen in the interaction of tel. As the power is in the world, and we can break the supplements of good power, it means that the value is valuable, as it can be changed. In which ones do you find strength?
One vimir sili
In honor of the English physicist Isaac Newton, who was victoriously majestic in the past in nature, when it was born and when it was born, 1 Newton (1 N) was taken for one. Well, is that a force of 1 N? Physics does not choose one for nothing, but for a while, hesitates the price of eating with those ones, as they are already accepted.
We know of the knowledge and experiments, that as soon as one could rest on a new strength, then only because of the process of changing its performance. Apparently, for visualization of strength, they chose one, as it would characterize the change of speed. It’s not forgotten, but it’s still and masa tila, so it seems like it’s pouring into different objects with the same force and it’s going to be different. The ball can be thrown far away, and the axis of the round timber can fly to the nabagato menshu vіdstan. So, having lost all the factors, we come to the value, but the force in 1 N will be applied to the floor, as the weight of 1 kg is poured into the flow, the force changes its speed by 1 m / s in 1 second.
A unit to vimir strong
So it’s a tough one to trick us into being alone. So as it is known that the Earth will attract to itself all the bodies on the surface, which means that the real power of heavy and it can be reduced. And again, we know, it’s hard to lay down the strength of the body. Chim is more masa tila, tim is stronger The earth attracts you. Experimentally installed, scho power is heavy, so for tilo masoyu 102 grams - tse 1 N. And 102 grams is about one tenth of a kilogram. And if it’s more accurate, then if 1 kg is divided into 9.8 parts, then if it’s just about 102 grams.
If the weight is 102 grams, the force is 1 N, then the weight is 1 kg, the force is 9.8 N. The acceleration of the vital fall is signified by the letter g. І g one 9.8 N / kg. Tse force, yak dіє for a weight of 1 kg, accelerating the skin for a second by 1 m / s. To walk, very quietly, falling from a great height, for an hour, the benefit is gaining even great speed. Why should the little ones and boards fall to finish spokyno? They have a very small masa, and the earth is even more weak. And the opіr of the fortune is for them to reach the great, that the stench to fly to the Earth with the small one, to finish the same shvidkіstyu. And the axis of the meteorite, for example, when it reaches the Earth, gains an even higher speed and when it is down, a decent vibuch appears, which is likely to lie in the size and mass of the meteorite.
Daniy is a good friend of children from children. On the other hand, a small book "Mass Radio Library" was seen in 1964, as the transfer of O. Kroneger's book to the People's Democratic Republic in 1961. Do not be astonished at such an old-fashioned thing, won’t be my book (order with a few cousins). I think for an hour on such books I do not possess, for that the fundamentals of physics, electrical and radiotechnics (electronics) are non-porous and vichni.

Physics yak science, yak vivchaє the laws of our Vsesvita, vikoristovu standard methodology of doslіdzhen i sing system odinits vimir. 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 the most famous 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 knowledge of the science of Isaac Newton.
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 a 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 necessary inflow of inspiration, then they will be known to be in peace. And as long as it was known in Russia, then when there is a rise in the daytime, I will pour it into a new one, I will continue to develop my equal ruh along 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 heavy, yak is straight down, and (in the given table), is straight up on the mountain. So, if they were offended, they were wrong to do one to one, then the value of the equal force would be 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 til, and for the quickened, as soon as I will take away the applied force. Isaac Newton, in 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, in order 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. When the values of the properties are close to the high quality 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 describes 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-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 knot 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 when we are going 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 power to the subject, on the way of the door, then it is immediately put і straight 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. In case of higher production facilities from mechanics, it is often necessary to convert Newton into the values of the newton. 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 vimir in the MTS system, 1 stin for road power, which is usually accelerated in 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, і before the new boule try to guess the secret of the earth's hard times. 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).
Isaac Newton was born on the 25th breast of 1642 (or on 4 June 1643 by the Gregorian calendar) in the village of Woolstorp, Lincolnshire.
