Gravitational force describes the interaction of one object with mass with another object with mass.
- a model used to explain the influence that an object extends into the space around itself, producing a force on another object. This force is always attractive.
- every particle attracts every other particle in the universe with a force
that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
