Why is the force of gravity noticeable between you and the Earth but not noticeable between you and a football?

a
The Force of Gravity only works because you are closer to the Earth than a football
b
The Force of Gravity only works on certain objects and a football is not one of them
c
The Force of Gravity cannot work in atmospheric conditions, only in space conditions
d
The Force of Gravity is only noticeable when objects have an immense mass, like planets do

a) The Force of Gravity only works because you are closer to the Earth than a football.

The correct answer is option a) The force of gravity is noticeable between you and the Earth but not noticeable between you and a football because the force of gravity is stronger when the objects are closer together. Since you are much closer to the Earth than you are to a football, the force of gravity between you and the Earth is noticeable, whereas the force between you and a football is much weaker and therefore not noticeable.
