Gravitational acceleration

Gravitational acceleration is a physical quantity that indicates the acceleration with which a body moves due to gravitational action. Gravitational acceleration is often denoted by the symbol "g" and is characteristic of any body or planet with mass.

The definition of gravitational acceleration is given by Newton's law of gravity, which states that the gravitational force acting on a body is directly proportional to the mass of that body and inversely proportional to the square of the distance between the bodies. Gravitational acceleration on the Earth's surface is approximately 9.8 m/s².

Gravitational acceleration is responsible for the gravitational force exerted on bodies and determines the speed with which bodies in free fall move towards the center of the earth. This means that when a body is released in free fall, its speed increases by the gravitational acceleration in each time interval.

Gravitational acceleration is a universal constant for all bodies near the Earth's surface and is one of the main factors affecting mass movements on Earth. It is also applied in physical calculations, astronautics, astronomy and other areas where it is necessary to study and model gravitational effects on bodies.
