The law of universal gravitation.

The law of universal gravitation describes the force of gravitational interaction between two bodies.

The online calculator below allows you to find:
- The force of mutual attraction through the masses of bodies and the distance between them;
- The mass of a body through the force of mutual attraction, the mass of another body and the distance between them;
- The distance between bodies through the force of mutual attraction and the mass of bodies.

The law of universal gravitation is one of the most fundamental laws of physics, which describes the attraction between all objects in the universe. This law was discovered in 1687 by Isaac Newton and remains one of the basic principles in the study of space physics and astronomy.

According to the law of universal gravitation, every object in the universe attracts another object with a force proportional to their masses and inversely proportional to the square of the distance between them. This means that the greater the mass of an object, the stronger it attracts other objects, and the greater the distance between objects, the weaker the force of attraction between them.

The law of universal gravitation is of great importance for our understanding of space physics and astronomy. It allows us to explain how the planets move around the sun, how satellites move around the planets, and how spacecraft can use the planets' gravitational fields to speed up or slow down their movement.

Also, the law of universal gravitation explains why we cannot fly without the help of technology - our bodies are attracted to the Earth with a force that is proportional to their mass. It also explains why our bodies stay on the ground instead of flying off into space.

In addition, the law of universal gravitation plays an important role in space exploration. It allows scientists to understand how planets and other objects in the universe interact with each other, and how their movement and evolution can be predicted in the future.

It is important to note that the law of universal gravitation is an idealized mathematical description of reality and does not take into account some effects such as air resistance, the rotation of the Earth and other factors. Nevertheless, it remains an important element of physical theory and is a key element in the study of space physics and astronomy.

In conclusion, the law of universal gravitation is one of the fundamental laws of physics, describing the attraction between all objects in the universe. It plays an important role in our understanding of space physics and astronomy, and allows scientists to predict the movement and evolution of objects in the universe.
