What Is The Importance Of Newton’s Laws?
Isaac Newton is one of the fathers of modern science and, thanks to him, have been able to explain some “mysteries” of nature and many more unknown until the application of its laws along with others. The discoveries of this scientist have explained the existence of gravity, the movements of planets, etc.
Newton’s first law, the Law of Inertia, tells us that every body is in a state of rest or, if it is in motion, it is rectilinear and uniform. The variation of this state is due to other forces exerted on it. Newton’s second law, Law of force, tells us that the change of movement is proportional to the driving force that is exerted. Newton’s third law, Law of action and reaction, tells us that every action implies an equal and opposite reaction (an example of this may be the force of a car when moving and the force of the air to stop it).
These laws are the basis of mechanics and have helped to understand the planetary movement when combined with the law of universal gravitation. In addition, Newton’s laws have also been instrumental in understanding and explaining how machines work.
When we look back and discover where we come from and the origin of everything we know, we know … we have no choice but to realize that these people who have dedicated their lives to research, with the primary resources available to them of his hand, with which his work has an added merit because, not only did they have to unravel the unknown, but they also had to face a society that, either for religious or other reasons, on many occasions rejected these discoveries.
That is why Newton’s laws have that historical and scientific value. They are part of the important big discoveries that only a few people can get. Anyway, all this is also the result of the collection of many knowledge of other places and civilizations that were available to very few. We have to think that at that time, unlike the current one, those who owned books to train and know the science of other authors and countries, were people of the upper class or religious, who were the only ones who could practically afford it.
For these and other reasons, he managed to draw up some laws, which have helped us a lot, with laboratory means that we would consider precarious today, but in spite of that he has taken advantage of every step he has taken, with his mistakes and with his successes , until getting results.
