Hamme hamm Sorry to say but ouer plant gravity isn't influenced from the whiget of the object it pulls! If we take 1kg object and 3 kg object they will fall in the same time BUT the difference that we see about different objects falling, a leafe and a big stone for example, is because there different in theirs S/V and the influence of air friction on them!
If we push a 1 ton bolder and 10 grams fether from the same higet IN VACUUM WITH NO AIR they will reach the bottom in the same time!
See this.
