Here are three key points to remember about gravitational forces in space:
-
Inverse Square Law: The strength of gravitational force between two objects decreases with the square of the distance between them. This means that if the distance between two objects doubles, the gravitational force between them becomes one-fourth as strong.
-
Mass Dependency: The gravitational force is directly proportional to the masses of the objects involved. This means that larger masses exert stronger gravitational forces. For example, a planet will exert a much stronger gravitational pull compared to a small asteroid due to its significantly larger mass.
-
Universal Gravitational Attraction: All objects with mass in the universe attract each other through gravitational forces. This attraction does not diminish in space; every object, from small asteroids to massive galaxies, is affected by and contributes to the overall gravitational field of the universe.
