gravity

When any matter or energy produces relative motion, it produces gravity. Note: 1. If the same kind of material or energy produces relative motion, it also produces gravity. 2. It applies to micro particles ranging from galaxy motion to atoms. 3. When a variety of substances are mixed, as long as there is relative motion between two objects or energy separated by other substances, gravity will also be generated. 4. The size of gravity is directly proportional to the mass and energy of matter, inversely proportional to the distance between…
