gravitational force acts on all objectsin proportional to their masses why does a heavy object not fall faster than a light one?

 for acceleration, we find: 

 

Which is proportional to m1/m2, i.e. the gravitational mass divided by the inertial mass. Now, if and only if m1/m2 is a constant for all objects, they will all fall at the same rate. If this ratio varies, then we will have no definite relation between rate of fall, and weight.
