The gravity of Earth, denoted by g, is the net acceleration that is imparted to objects due to the combined effect of gravitation (from mass distribution within Earth) and the centrifugal force (from the Earth's rotation).
It describes the strength of the gravitational forces that a massive object exerts at any location around it. Its value can be quantitatively described by an equation that derives from Newton's second law combined with Newton's universal gravitation equation.
3 lut 2023 · What is Gravitational Force? All objects having mass attract each other with force known as the gravitational force. It is quite noticeable in astronomical objects such as Sun, Earth, and Moon that have enormous masses. The reason is that the force is proportional to the products of the objects’ masses.
Newton's law of universal gravitation states that every particle attracts every other particle in the universe with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
It means that gravity stands apart from the other three fundamental forces, electromagnetism and the strong and weak nuclear forces, which are quantum forces, described by quantum field theory...
The value of G is an incredibly small number, showing that the force of gravity is very weak. The attraction between masses as small as our bodies, or even objects the size of skyscrapers, is incredibly small.
Gravity: the attraction of objects with mass or energy towards each other. This attraction shows as a force that is: less for objects that are further away.
