What is terrestrial gravity

Terrestrial gravity is the force of attraction that the Earth exerts on all objects that have mass, keeping them stuck to its surface. As a force, it is also known as the force of gravitation or the force of gravity. It is responsible for the fact that, when an object is dropped, it inevitably falls to the ground, as well as the seas, the atmosphere and even our own bodies remain attached to the planet. It is a very weak force compared to other fundamental forces, such as the electromagnetic force, but its range is infinite.

Law of universal gravitation

According to Newton’s law of universal gravitation, the gravitational force between two objects is directly proportional to the mass of each object and inversely proportional to the square of the distance between them. That is, the greater the mass of an object, the greater the gravitational force it exerts, and the greater the distance between two objects, the smaller the gravitational force acting between them.

Importance of gravity

The force of gravitation is responsible for keeping the planets in orbit around the sun and for keeping us glued to the surface of the Earth. Without gravity, the planets would move in straight lines instead of following elliptical orbits, and we would float in space instead of being attached to the surface of the Earth.

Understanding gravity is essential to our understanding of the large-scale universe. Gravity is crucial in the formation of galaxies and the structure of the universe as a whole. Understanding how gravity works helps us explain phenomena such as the formation of black holes, the interaction of stars and galaxies, and the expansion of the universe.
