The relationship between gravitational force and distance of separation is an "inverse relationship".
<u>Explanation:</u>
Gravitational force has been explained by "Newton's Universal Law of Gravitation" which says "In this universe every single particle attract every other particle with a force which directly proportional to the product of their masses while inversely proportional to the square of the distance in between them".
The gravitational force is inversely proportional to square of distance because as the distance between the objects with masses increases the force decreases. The gravitational force between any two objects with masses can be understood by given formula:
Here the F is gravitational force,
G is the gravitational constant =
are the masses of the two objects
d is the distance between two objects.
Answer:
A star's brightness also depends on its proximity to us. The more distant an object is, the dimmer it appears. Therefore, if two stars have the same level of brightness, but one is farther away, the closer star will appear brighter than the more distant star - even though they are equally bright!
