Why don't rains kill despite the fact that they exhibit free fall?

Answer 1

Weight; rain is very light.

If I drop a bunch of feathers on your head then it isn't going to hurt you, even if I drop them from a huge height. Raindrops are very small and very light so they don't damage people, unless they are a whole lot of them. A driving rain is a storm that has enough rain to provide a strong force on someone or something. Driven by wind or heavy rain a driving rain can force a car off the road, or push a person down by providing a force just strong enough to disturb their normal movement.

Ice weighs more than a few rain drops and when rain freezes it can form snow or if a lot of it freezes in a clump then hail. Hailstones are like small stones and some of them fall with enough strength to break glass. It is common for them to dent cars and break their windshields.

Answer 2

In order for a raindrop sized bunch of water molecules to hurt or seriously injure someone you have to exceed its terminal velocity i.e. put a 200 mph wind behind it.
