Eli5:Why does a deflated balloon fall to the ground at normal speed like other things do, but when full of air floats longer even though the balloon stays the same mass?

Eli5:Why does a deflated balloon fall to the ground at normal speed like other things do, but when full of air floats longer even though the balloon stays the same mass?

In: Physics

Answer 1

for the same reason that a piece of paper falls down slowly, it has a low weight-to-surface ratio. In a vacuum everything falls down at the same speed but because of air resistance they don’t on earth. Because an inflated balloon has the same weight but a higher surface it has more air resistance and falls more slowly.
