Gravitational force is a fundamental force of nature that exists between any two objects with mass. It is the force that attracts objects towards each other. According to Newton's law of universal gravitation, the gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
The equation for gravitational force is F = G * (m1 * m2) / r^2, where F represents the gravitational force, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between their centers.
Gravitational force is responsible for various phenomena, such as the gravitational attraction between the Earth and objects on its surface, the motion of planets in the solar system, and the formation of galaxies. It is a crucial force in understanding the behavior of celestial bodies and the dynamics of the universe.
