Answer to Question #16065 in Mechanics | Relativity for Maree
How do masses interact with each other?
The masses interact with each other due gravity force. Gravitation, or gravity, is a natural phenomenon by which physical bodies attract each other with a force proportional to their masses. Gravitation is most familiar as the agent that gives weight to objects with mass and causes them to fall to the ground when dropped. Gravitation causes dispersed matter to coalesce, and coalesced matter to remain intact, thus accounting for the existence of the Earth, the Sun, and most of the macroscopic objects in the universe.
