Raindrops typically fall at speeds between 15 and 25 miles per hour (mph), depending on their size.
Here's a more detailed look:
-
Terminal Velocity: Raindrops reach a terminal velocity as they fall, meaning the air resistance balances the force of gravity. This prevents them from accelerating indefinitely.
-
Size Matters: Larger raindrops fall faster because they have a greater mass relative to their surface area (which determines air resistance).
- A smaller raindrop with a radius of 0.15 cm has a terminal velocity of about 7 meters per second, which is approximately 16 mph. (Referenced)
-
Speed Range: While factors like size and air density affect the exact speed, raindrops generally fall between 15 and 25 miles per hour, regardless of the cloud height from which they originate. (Referenced)

|---|---|
| Small | Around 15-16 mph |
| Typical | 15 - 25 mph |
