Raindrops fall from the sky because of gravity. The water droplets in clouds are constantly bumping into each other and growing larger. When the droplets get too large, they can no longer be held up by the air currents in the cloud and they fall to the ground as rain.

The size of a raindrop affects how fast it falls. Smaller raindrops fall more slowly than larger raindrops. This is because the drag force, which is the force of the air resistance, is greater on smaller raindrops.

The speed of a raindrop also depends on the wind. If the wind is blowing upwards, it can slow down the raindrops. If the wind is blowing downwards, it can speed up the raindrops.

The average speed of a raindrop is about 7 meters per second (15 miles per hour). However, the speed can vary depending on the size of the raindrop, the wind, and the altitude.

Here is a summary of the factors that affect the fall of raindrops:

• Gravity: The force of gravity pulls the raindrops towards the Earth.
• Air resistance: The force of the air resistance opposes the force of gravity.
• Size of the raindrop: The larger the raindrop, the faster it falls.
• Wind: The wind can slow down or speed up the raindrops.
• Altitude: The higher the altitude, the faster the raindrops fall.
