Expert Answer:

Let the gravitational force between earth and apple be F, and M be the mass of earth and m that of apple.

The acceleration of apple, with which it's pulled towards earth = F/m

The acceleration of earth, with which it's pulled towards apple = F/M

Since acceleration is inversely propotional to the mass, we see the acceleration induced in earth is very very small.

But it's not so for the apple. Hence the motion of apple, downward fall is only noticeable.
