What is the gravitational force?

The gravitational force is an attractive force between two separate bodies in the simplest sense. Gravity is related to matter: The greater the matter of the object, the greater the gravitational force that develops on other objects. It is one of the basic forces that are responsible for the structure of the universe. Although it is one of the easiest observable cosmic forces, gravitational principles are still not fully understood by modern science. Galileo, a few decades earlier, showed that objects are falling the same degree, regardless of their weight. The fall of Apple inspired Newton to study the gravitational force, although the apple did not actually hit the head and brought immediate understanding; He spent more than 20 years on this topic. He realized that the gravitational force also held the moon in orbit around the Earth, and Wjak could do it by means of orbit to check its calculations.

Newton realized the same principles applied to allobjects everywhere in space; His theory became known as the law of universal gravity. However, he freely admitted that he did not understand how the gravitational force was handed over from one object to another, seemingly immediately, despite huge distances. Despite this defect, Newton's law has become an established scientific principle for the next three centuries. It has repeatedly proved to be the correct predication of, for example, the location of planets that have not yet been discovered.

Newton's law, albeit correct in most general applications, contained minor inconsistencies that became obvious because the progressive science was more accurate. Einstein, who worked in the early 20th century, finally was responsible for these inaccuracies with his theory of general relativity. Depending on the relaat, the movement of the space of the universe is controlled by the effect of these bodies on the structure of space -time. Newton's law is still used by scientists because it is easier to calculate them and is correct for such practical matters as the great power of the rocket must leave the Earth's atmosphereu.

Neither Einstein fully explained the gravitational force. In modern times, gravity is one of the four basic forces that combine the universe together, along with electromagnetism and weak and strong nuclear forces. The latter three were demonstrated by the discovery of sub-atomic particles that mediate these forces for distance. A similar particle for gravity, the so -called graviton, has remained elusive since 2010. Other principles of gravitational forces remain also unexplained modern physics.
