Question

Why moon does not fall towards earth? ​

Answer 1

Because the moon's gravitational force field radius overlaps with the gravitational field radius of the earth.

Step-by-step explanation:

It is only when a body is within the radius of the earth that it can get attracted to the earth but when it is out of its radius it can't exert any force on the body. The force decreases as a body moves out of its radius. Therefore the Earth's gravitational force is minimum at its gravitational radius. The moon can't fall towards the earth because:

1: it is not the moon itself that overlaps the Earth's gravitational force field radius but the moon's gravitational force field radius.

2: Although the earth has a minimum force of attraction at its radius that it can use to pull bodies towards itself but the moon also at its radius has a minimum force equal to that minimum force of the earth that it can use to pull bodies to itself .

3: The overlapping of their gravitational force field caused the equilibrium between the two forces they exert inwardly on each other.

Answer 2

See exp.

Step-by-step explanation:

The moon has a sideways gravitational pull on earth and so does the earth. But, their velocity or motion is not perpendicular.

The distance between the earth and its moon is long! Therefore, the gravitational force is less. Even though the Moon's own gravitational pull on the earth causes tides in oceans.

Hence, distance and the direction of force matters.
