【英语时差8,16】哪一个先落地？（下）

Why not? You cry.Well,ask yourself this question: which one is easier to move in the first place? The golf ball. So it takes more force to move the bowling¹ ball. And the bowling ball is also the one gravity pulls on more. See the connection? A more massive object has more stuff for gravity to act on. But because it is more massive, it is also that much harder to move! A smaller object is easier to move. But it also has less stuff for gravity to act on! The cool thing is these two factors exactly balance each other out. And that’s why any object, from dump trucks to linguini, falls at exactly the same rate as any other object.
