Both stones have the same acceleration (gravity) but the the 5 gram stone falls over 100 meters and builds up higher speed; and although the 10 gram stone s heavier the energy is much higher at impact for the 5 gram stone. The energy is simply

E = mgh wher m = mass; g = gravity acceleration and h = distance.

Since both have same gravity acceleration, you can see that energy is higher for the 5 gram stone;

mgh = 500 g for 5 gram stone

mgh = 10 g for 10 gram stone
