If you dropped a bowling ball and a feather from the top of a tall building, which do you think would hit the ground first? It’s pretty safe to assume that it would be the bowling ball, as you’d think the feather would gently waft down to the ground while the bowling ball would plummet down. And that is exactly what would happen. But even though the objects would hit the ground at different times, in fact, all objects actually fall at the same speed, no matter what their mass is. The different falling speeds we witness as the objects drop is all to do with air resistance.
