the more massive they are, the more attraction they have
For every doubling of distance, the "force of attraction" is reduced by a factor of four. For every halving of distance, the "force of attraction" is increased by a factor of four.
The gravitational force is a natural phenomenon by which objects with mass attract one another. It is responsible for keeping planets in orbit around the sun and objects on Earth grounded. The force of gravity follows Newton's law of universal gravitation, which states that every mass attracts every other mass with a force proportional to their masses and inversely proportional to the square of the distance between them.
The moons gravitational attraction is weaker as the moon is smaller
All objects with mass attract all other objects with mass. The force between two 1-kg masses 1 metre apart is 6.670E-11 Newtons. All gravitional forces are attractions, unlike electric or magnetic attraction that can be attraction or repulsion. Thus gravitation is the only force that could have caused the stars to form.
Mass and Distance
The attraction between two objects is called force of attraction or gravitational force.
At a larger distance, the gravitional force gets smaller.
The attractive force of matter is the gravitional forces between the two masses. The force of the attraction is inversely proportional to the square of the distance. You are pulling the Earth toward yous with the same proportionate attraction that the Earth is pulling you, relative to each of your own relative weight. See Cavendidh's experiment on the attraction of masses.
The three factors are the mass of the two objects and the distance between them.
All objects have gravity and gravity depends on the mass of an object and the distance between the object.
The force of attraction between objects that is due to their masses is Gravity!
There are two factors that affect the gravitational attraction between two objects. The mass of each object and the distance between their centers of mass are the factors that affect the attraction.
