Only the Mass of the Raindrop Determines Distance Miterwort Seed Travels
In the interest of accuracy, I am going to risk boring readers with a clarification of what determines the distance that a Miterwort seed travels. Jim Block, an outstanding nature photographer, obviously has a greater grasp of physics than yours truly. I attributed the distance traveled to the size of the raindrop and the distance it had traveled, but as Jim so clearly explains, only the the size of the raindrop effects the distance the seed travels.
Here is his explanation: The distance the seed travels is likely dependent on the mass and the velocity of the drop when it hits the seed. But the velocity of the rain drop is only dependent on its mass, not the distance it falls. That is because after it falls a relatively short distance it no longer gains speed since the air drag balances gravity and the drop moves at a constant “terminal velocity”. So in effect the distance the seed travels is dependent only on the mass of the drop. All drops of the same size arrive at the same velocity.
