Two forces act on a raindrop. One is gravity which is constant, the other is the friction from the air, which is opposed to gravity. The latter is proportional to the speed of the drop and the surface area.
During it´s fall the speed increases and therefore the drag. In the end the two force are equal and the drop continues to fall with constant speed.

They have reached their terminal velocity. A rain drop can only accelerate for so long before it's mass can no longer make it go faster, so the velocity is constant.

its called "terminal velocity". an object that is dropped will accelerate until it reaches a speed at which air resistance stops the acceleration, then the object falls at a constant speed. terminal velocity is also determined by the object's shape.

lemme tell u this is b'cos rain drops falling from height store a great potential to move with hi velocity.this is like if we drop aball from a great height it falls with a great speed and if catcht it it hurts..........


so simple

because they all have the same weight, unlike snowflakes...
and they are all under the same pull of gravity...
