What two factors determine the strength of gravitational force between two objects?

Explanation:
Gravitational attraction between two objects is determined by how much stuff they contain and how far apart they are. In Newton’s law, the force is proportional to the product of the two masses and inversely proportional to the square of the distance between their centers: F = G m1 m2 / r^2. This means bigger masses pull harder, and increasing the distance makes the pull weaker very quickly (doubling the distance reduces the force by a factor of four). The speed or motion of the objects doesn’t change gravity, and electric charge governs electric forces, not gravity.
