The **gravitation** is he **act and consequence of gravitation**. In the field of **physical**, gravitation is the **attraction of bodies according to their mass**.

It can be said that gravitation or **gravity** It is a phenomenon of nature by which bodies with mass attract each other. It is one of the **fundamental interactions** that occur in the natural environment. The orbit of the Earth around the sun and the orbit of the Moon around the Earth, for example, are produced by the effect of gravitation.

The physical **Albert Einstein** and **Isaac Newton** proposed the **theories** more widespread on gravitation. It is important to note that this natural phenomenon provides cohesion and unity to the universe.

To understand how gravitation works, you must first know how to distinguish between the **dough** (the amount of matter that a body contains) and the **weight** (a force that depends on the mass of the planet where it is measured). The gravitational interaction or force of gravity is the attraction that is registered in the bodies according to their mass.

It is known as **universal gravitation law** to the description of the gravitation that he formulated **Newton** in **1687**. This Newton’s law establishes a quantitative relationship, which he deduced empirically through observation, between the attractive force and the **bodies** with mass that attract. According to **Newton**, this force depends on the value of the masses of the attracting bodies and the square of the distance that separates both.

Isaac Newton formulated the law of universal gravitation in a book he titled *Philosophiae Naturalis Principia Mathematica*, whose official translation into Spanish gives us *Mathematical principles of natural philosophy*. When the bodies are at a considerable distance, Newton points out that the force of gravity acts in a very approximate way, as if the total mass of each one were found exclusively in the **center**, that is, as if it were two points. This insight allowed him to considerably simplify the calculations of the interactions between any pair of objects.

The **formula** that summarizes what has been exposed so far can be seen in the second image of this document. Its interpretation is as follows: the force that can be seen between two bodies of different masses located at a certain distance is equivalent to the multiplication of their masses and also inversely proportional to the distance squared. The variable **F** represents the module of the force exerted by the two bodies (the module is a value that is equal to the length of the force vector), and its direction is found on the axis that joins them; with respect to **G**, is the **universal gravitation constant**.

In the field of physics, it is known by the name of **universal gravitation constant** to the value that is obtained empirically to determine the intensity with which bodies attract. It should be noted that this variable is found in both Newton’s and Einstein’s theory. Its origin dates from the year 1798, and its discovery is attributed to the physicist and chemist **Henry Cavendish**, born in France in 1731 and later nationalized English. While this constant is one of the oldest, its value is far from accurate even today.

Beyond physics, the concept of gravitation is used to refer to the **influence** that something or someone exercises: *“The gravitation of the Minister of Economy in the government is undeniable”*, *“I think the presence of the Belgian forward will give another gravitation to the team’s offense”*, *“The comments of this religious fanatic have no influence in our community”*.
