Is the relationship between gravitational force and distance of separation and inverse or direct relationship?

The relationship between gravitational force and distance of separation is an "inverse relationship".

Explanation:

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.

the answer is kevlar

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
