From Newtons's second law of motion , it can be cancluded that the acceleration produced in a body is inversely proportional to the mass of the body `("because " a =F/M)`. Now due to the very large mass (m) of the earth , the gravitational force (F) between the moon and the earht produces very small acceleration (a) in the earth .Actually , the accelertion produced in the earth (by the attraction of moon) is so small that it cannot be observed .And hence we do not see the earth move towards the moon .
