The units in the International System of Units, known briefly as SI, determine the units that are accepted as common in most of the world or correspond to themselves in some way. These ensure a global understanding of assessments in basic fields such as mathematics, physics and chemistry. One of the units in this system is the Newton force unit, shown with the symbol N.
No surprise, the name Newton unit comes from British physicist Isaac Newton. Because throughout his life, he worked in many different fields of science, especially physics, and determined some rules known today as Newton’s Laws. Let’s examine in full detail what the Newton unit is, which shows the force required to move an object at a certain acceleration and is still used today, how it is shown, and what Isaac Newton’s Laws are.
Let’s start by briefly defining it: What is the Newton unit?
In the International System of Units, absolute force is represented by the unit Newton. It can also be defined as the force required to accelerate one kilogram mass by one meter per second, that is, to move that mass. This unit is named after the English physicist Isaac Newton because he was one of the first to explain the changes that a force can cause in the motion of an object.
How is the Newton unit, also known as the unit of force, represented?
The Newton unit, also known as the force unit, which indicates the force required to move an object at a certain acceleration, is shown with the symbol N in the International System of Units. The International System of Units is considered a contemporary version of the metric system. In addition to force, this system contains many units of values such as time, mass, length, electric current, temperature, amount of matter, light intensity, and combinations of these units.
So how many kilograms is 1 Newton? Here are Newton’s formulas for different units:
- 1 N = 1 kg xm/s²
- 1 N = 10⁵ dyn
- 1 N = 0.10197 kg-f
- 1 N = 0.22481 lb-f
- 1 N = 7.2330 pdl
- 1 kg-f = = 9.80665 N
- 1 lb-f = 4.448222 N
- 1 pdl = 0.138255 N
Newton’s laws of motion:
- Law 1: Inaction
- Law 2: Mass resistance
- Law 3: Action reaction
Law 1: Inaction
Inertia, which constitutes Newton’s first law, is whether an object continues its linear motion or does not move when it is not subjected to an external force. If the object is at rest, its speed is zero; if it is moving in a fixed direction, its speed is constant. If no force is applied to the object, it will remain at rest or continue moving without changing its speed and direction.
The law of inertia is generally explained with the example of a sled. A sled that is released from a snow-covered hill continues on its way at a constant speed without changing direction unless any force is applied. However, as it will naturally be exposed to the friction force, it will slow down and eventually stop. However, in an environment where there is no force, its speed does not change.
Law 2: Mass resistance
Newton’s second law, mass resistance, states that the acceleration caused by the force applied to an object is inversely proportional to the mass of that object. In other words, the greater the force applied to an object, the greater the acceleration will be, but the greater the mass of the object, the smaller the acceleration will be. This law is shown by the formula F = ma.
Of course, this formula directly refers to situations where the mass is constant. The second law also covers different topics such as thrust, variable mass systems, relativity, open systems. Each has its own formula, but basically focuses on the relationship between mass and force.
Law 3: Action reaction
Newton’s third law, action and reaction, actually states that force is two-way. In other words, for every action there is a reaction in the opposite direction, and this effect and reaction may be equal. That is, object X applies a force to object Y, and in the same way, object Y applies a force to object X. This action occurs even if the reaction situation is not a balanced force.
Let’s say there are boxes X and Y sitting side by side on a frictionless surface. X has a mass of 4 kg and Y has a mass of 2 kg. Box X is pushed towards box Y with a force of 30 N. In this case, both boxes already have a force exerted on the ground and a horizontal force. While box X pushes box Y, box Y also pushes box X. When we take other variables into account, box
What did Isaac Newton, who gave his name to the unit of force, do?
Isaac Newton was born in England on January 4, 1643; He is a philosopher and inventor who worked in the fields of mathematics, physics, astronomy, alchemy and theology. His work Philosophiæ Naturalis Principia Mathematica, in Turkish, titled Mathematical Principles of Natural Philosophy, which he wrote in 1687, not only established the rules of basic physical mechanics, but also became the most important book in the history of science.
Universal gravity and the rules of motion put forward by Newton, today called Newton’s Laws, have been the mainstay of many scientific fields, including physics, for hundreds of years. Isaac Newton, who also invented the first known reflecting telescope, came up with the color theory by seeing that white light turns into different colors when it passes through a prism.
Even though his work was criticized from time to time, it was later accepted and deemed important enough to be appointed head of the Royal Society and given the title of knighthood. Sir Isaac Newton passed away on March 31, 1727, at the age of 84.
We talked about the work done by Isaac Newton, who gave his name to the unit, by asking questions such as what is the Newton unit with the symbol N, which is the unit of force in the International System of Units, and how is it represented?
