Gravity is a force pulling together all matter. The more matter is, the more gravity it takes. Gravity is depending to mass. There are two forces in nature that we experience every day: gravity and magnetism. You may have magnets on your refrigerator, and you know that a magnet will attract a refrigerator with a certain amount of force. The force depends on the strength of the magnet and the distance between the magnet and the metal. You also know that magnets have two poles -- north and south. Either pole will attract iron or steel equally well; north will attract south, and like poles will repel one another. Gravity is the other common force. Newton was the first person to study it seriously, and he came up with the law of universal gravitation:
Each particle of matter attracts every other particle with a force which is directly proportional to t al to the square of the distance between them. His product of their masses and inversely proportion
The standard formula for gravity is:
Gravitational force = (G * m1 * m2) / (d2)
