Space Assessment #3 Study Guide
What happens to the force of attraction if the distance between 2 objects is increased?
So as two objects are separated from each other, the force of gravitational attraction between them also decreases. If the separation distance between two objects is doubled (increased by a factor of 2), then the force of gravitational attraction is decreased by a factor of 4 (2 raised to the second power).
What determines the gravitational attraction between the Earth and other objects?
The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases.

What determines the number of moons a planet has?
This is quite simple if you think about it. Density for one is a determinant. How dense the planet the satellite is orbiting will very much likely determine the moons it will have. The more dense, the more the number (assuming the moons are made up of lesser dense elements) The density ratio between the planet and satellite. The greater the ratio, the more likely the planet could sustain more moons within a given ratio. Position from the star it's orbiting. The further away it is, the lesser moons it will/could have. It should not be too close or too far. A median distance preferably. Orbital distance. If the orbit of the current moon is larger, the planet could most likely sustain another satellite of a particular size and density. Smaller orbits make it difficult to have many moons.
What force holds the planets in orbit?
gravity Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.
