What is gravity and laws of gravity?
Gravitation is a natural phenomenon by which objects with mass attract one another. In everyday life, gravitation is most commonly thought of as the agency which lends weight to objects with mass. Gravitation compels dispersed matter to coalesce, thus it accounts for the very existence of the Earth, the Sun, and most of the macroscopic objects in the universe. Law of gravity is: Every point mass attracts every other point mass by a force pointing along the line intersecting both points. The force is directly proportional to the product of the two masses and inversely proportional to the square of the distance between the point masses: F=G x m1 x m2/r2 (r2 is r square) where: F is the magnitude of the gravitational force between the two point masses, G is the gravitational constant, m1 is the mass of the first point mass, m2 is the mass of the second point mass, and r is the distance between the two point masses.
