Document Summary
There is a gravitational attraction between any two objects. Inverse-square law: mathematical relationship in which one variable is proportional to the inverse of the square of another variable. Force is inversely proportional to the square of the distance between the mass centers. The force of attraction drops quickly as the two objects move farther apart. Gravitational field: a collection of vectors, one at each point in space, that determines the magnitude and direction of the gravitational force. Gravitational field strength: the magnitude of the gravitational field vector at a point in space.
