* Air Resistance: The primary source of friction for a raindrop is air resistance. While air resistance does increase with speed, the small size and relatively low speed of raindrops means the force is minimal.
* Gravity: Gravity is a constant force acting directly downwards on the raindrop, pulling it towards the Earth.
* Terminal Velocity: Raindrops reach a terminal velocity, where the force of air resistance balances out the force of gravity. At this point, they fall at a constant speed. This wouldn't be possible if friction were equal to or greater than gravity.
In summary: While friction does play a role in the motion of a raindrop, it is much weaker than the force of gravity. This is why raindrops fall downwards and don't just float in the air.
