Definition - Term Overview


Physics is a term that comes from the Greek phisis and means "reality" or "nature. " It's about science that studies the properties of nature with the support of mathematics. Physics is responsible for analyzing the characteristics of energy, time and matter, as well as the links established between them.

For example: "Tomorrow I have to take a physical exam", "The vase fell by the laws of physics", "A physicist warned that a movement at that speed creates a risk for the athlete. "

This science doesn't only develop theories: it's also a discipline of experimentation. Their findings, therefore, can be verified through experiments. In addition his theories allow to establish forecasts on tests that are developed in the future.

Thanks to its vast reach and its extensive history, physics is classified as a fundamental science. This scientific discipline can be dedicated to describe the smallest particles or explain how a star is born, for example. Galileo Galilei, Isaac Newton and Albert Einstein have been some of the most recognized physicists in history. The original development of physics, however, was left to the Greek philosophers.

In this sense, it should be noted, for example, the figure of Empedocles who was a Greek philosopher and physicist who carried out the demonstration of the existence of air. And he did it by means of a contraption that received the name of clepsydra, which was a sphere of copper that filled with water when it was submerged in that liquid and that was characterized by having holes in the bottom and an open neck.

Thus, with it, he showed that when the aforementioned sphere was removed from the water without covering the neck, the liquid exited through all the mentioned holes. However, when the same operation was done but the neck was covered, the water didn't come out because the air was responsible for blocking the passage of the liquid.

In the same way, you can also talk about another physicist of antiquity as would be the case of Democritus. This is considered as the father of the atomist school and what he did was to expose that the aforementioned atoms can't be divided at any time.

Relativity (which takes into account the field of space-time and the interrelationships of gravity), electromagentism (studies light and other electromagnetic issues), classical mechanics (focuses on the displacement of bodies) and quantum mechanics (specialized in the atomic universe) are part of the main theories of physics.

In addition to all the above, it should be stressed that we also use the physical term to form, together with other words, terms of great use in our current society. Thus, for example, we talk about Physical Education to refer to the educational subject that revolves around exercises and knowledge to achieve a good body development.

Nor should we forget the expression Physical Geography, which is that part of the aforementioned geography that focuses basically on the configuration of the seas and the earth.
