Newton's Law of Gravitation
Newton's Law of Gravitation stands as a cornerstone in the realm of physics, presenting a universal framework for understanding the force governing the attraction between masses. Formulated by Sir Isaac Newton in the 17th century, the law states that every particle of matter in the universe attracts every other particle with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. This elegant equation, expressed as F = G * (m1 * m2) / r^2, not only explains the gravitational interactions on Earth but extends its applicability to celestial bodies, profoundly influencing the study of astronomy and the understanding of cosmic dynamics.
