|G||6.67 x 10^-11 m^3kg^-1s^-2|
|m1||5.97 x 10^24 kg|
F=((6.67 * 10^-11)*(5.97 * 10^24)*(0.001))/6360001^2
a1=(6.67 * 10^-11)*(0.001)/6360001^2
a1=1.65 * 10^-27 m/s^2
a2=(6.67 * 10^-11)*(5.97 * 10^24)/6360001^2
Notice how tiny the acceleration of the Earth is compared to the acceleration of the pencil. This is why we can't tell that the Earth is moving towards the pencil. Also notice how close the acceleration of the pencil is to the accepted average value for the acceleration of gravity on the Earth's surface (9.81 m/s^2)!
