Gravitational force acts on all bodies in proportion to their masses. Why, then, doesn't a heavy body fall faster than a lighter body?

Acceleration of an object is the ratio of net force acting on it to its mass. When the objects are falling, the only force acting on them is the force of gravity, neglecting air resistance. The reason why a heavy body doesn't fall faster than a light body is because the greater gravitational force on the heavier body acts on a correspondingly heavier mass(inertia). The ratio of gravitational force to mass is the same for every body so that all bodies in free fall accelerate equally. This can be proved as follows.
