Definitions for "Gravitational force"
The force that keeps you pinned to your seat and keeps the planets in orbit around the Sun. It could be carried by a gague boson called a graviton. Also, it is the weakest force to act on particles, so its effects are only measurable with extremely large objects. See also: graviton, gague boson
The force that occurs as a result of the attraction between objects due to their masses.
the weakest of the four fundamental forces of nature. Described by Newton's universal theory of gravity, and subsequently by Einstein's general relativity.
Long-range, believed to be mediated by the massless graviton, whose existence has not yet been confirmed by experiment.
