What is universal gravitaion?

Answer 1

Universal gravitation is a fundamental principle in physics formulated by Sir Isaac newton, stating that every mass attracts every other mass in the universe with a force proportional to the product of their masses and inversely proportional to the square of the distance between their centers. This force is described by the equation ( F = G \frac{m_1 m_2}{r^2} ), where ( F ) is the gravitational force, ( G ) is the gravitational constant, ( m_1 ) and ( m_2 ) are the masses, and ( r ) is the distance between their centers. Universal gravitation explains the motion of celestial bodies, the orbits of planets, and the behavior of objects on Earth. It laid the groundwork for modern physics and our understanding of gravitational interactions.
