Okay I am no physics pro, but Galileo claimed/proved that two objects of differing mass will fall at the same rate/speed. As I understand the force of gravity is a function of mass and distance. There is gravitational pull between all objects and this force is determined by the mass of the objects and their distance from each other. If I understand this then gravitational pull would be greater on an object of greater mass. Now I can see why Galileo's tests showed no difference as the the difference in mass of any two objects he tested would be insignificant compared to the mass of the earth. What am I missing here? Thanks for your help and please don't get too technical.
