A falling snowflake or raindrop does not accelerate as it approaches the ground because their mass doesn't change. The form is not affected throughout the fall so it is already approaching the ground at terminal velocity.

As the raindrop falls, it reaches a terminal velocity where the force of gravity pulling it down is balanced by air resistance pushing back up. At this point, the raindrop no longer accelerates and falls at a constant speed.
No, a raindrop is not a solid. It is a liquid that forms when water vapor in the atmosphere condenses and falls back to the ground as droplets.
As a raindrop falls, it may lose some thermal energy due to air resistance and evaporation, especially if the air temperature is lower than the temperature of the raindrop. However, the main energy change during the fall of a raindrop is potential energy being converted to kinetic energy.
A raindrop typically travels horizontally for a short distance, usually less than a few kilometers, before hitting the ground due to gravity and air resistance. The exact distance can vary based on factors like wind speed, size of the raindrop, and height from which it falls.
Objects accelerate as they fall to the ground due to the force of gravity acting on them. As the object falls, the force of gravity causes it to increase in speed, resulting in acceleration. This acceleration is a result of the unbalanced force acting on the object.
When you begin to walk forward, the force exerted by your leg muscles on the ground generates a reaction force that propels you forward. This force pushes against the ground, causing your body to accelerate in the direction you are walking.
