Gravitational force is the attractive force that exists between any two objects with mass. It is one of the fundamental forces of nature and is described by Newton's Law of Universal Gravitation. According to this law, the gravitational force (F) between two masses (m₁ and m₂) is directly proportional to the product of their masses and inversely proportional to the square of the distance (r) between their centers. The formula can be expressed as:
\[ F = G \frac{m_1 m_2}{r^2} \]
where \( G \) is the gravitational constant, approximately equal to \( 6.674 \times 10^{-11} \, \text{N(m/kg)}^2 \).
Gravitational force is responsible for the attraction between celestial bodies, such as planets, moons, and stars, as well as influencing objects on Earth. It governs the motion of planets in their orbits, the falling of objects toward the ground, and determines the structure of galaxies and the universe at large.
