Why do we say “collision-coalescence” and not just “collision”? Falling Raindrops ± What does “terminal velocity” mean? ± Which falls faster, little droplets or big droplets? ± How does a cloud droplet grow to raindrop size in a cloud when no ice is present? ± Sometimes a falling droplet does not collide with a droplet beneath it.
