How are objects around you affected by the mass of earth

All things are pulled by Earth's gravity.

Explanation:

All things are affected by Earth's mass through its force of gravity!

You can see this in the equation for the force of gravity:

F = (G•M•m) / r^2

G is the gravitational constant, r is the distance between the two objects affecting each other, but M and m represent their masses.

As either of the masses increase, so does F, the force of gravity.

So, all objects around you are directly affected by the Earth's mass through gravity.
