Gravitational Forces

Gravitational forces are a fundamental type of force that acts between two objects with mass. According to Newton’s Law of Universal Gravitation, every point mass attracts every other point mass by a force acting along the line intersecting both points. This force is proportional to the product of the two masses and inversely proportional to the square of the distance between them.
