As we saw, Galileo also claimed that all objects, light or heavy, fall with the same acceleration, at least in the absence of air. If you hold a piece of paper horizontally in one hand and a heavier object in the other, and release them at the same time, the heavier object will reach the ground first. But if you repeat the experiment, this time crumpling the paper into a small wad, you will find that the two objects reach the floor at nearly the same time.
