It does, up to a limit called "terminal velocity". Terminal velocity is reached when the force of friction against the air equals the force of gravity acting on the raindrop.
As the drop falls, it hits molecules in the air, and each of those molecules slows the raindrop down just a little bit. As gravity pulls the drop down, soon it hits so many molecules per unit of time that the combined effect prevents it from gaining any more speed.
The viscosity of air provides a drag force on a raindrop and keeps it from falling with the acceleration of gravity. When a drop is falling (assuming it does not combine with other drops in the process) it will reach a terminal velocity which depends on its diameter. The larger the diameter the larger the terminal velocity. Specifically, the terminal velocity is proportional to the square root of the diameter of the drop. Big rain drops fall faster than small rain drops. See related links for details and equations.
If the raindrop is falling at a constant speed, then it has reached terminal velocity. This happens when the downward force (due to gravity) is the same as the upward force due to friction. As such the net force acting on the rain drop is 0.
free fall
The size and shape of the raindrop, air resistance, and gravity all affect the speed at which raindrops fall. Larger and more aerodynamic raindrops fall faster due to their mass and streamlined shape, while smaller raindrops may be slowed down by air resistance. Gravity also plays a crucial role in determining the speed of fall.
there is a lot of difference between fall and flow... normally we use fall for the object moving without any support and in an angle nearer to 90 degree downwards.. whereas flow is moving with support nearer to 0 or 180 degree... Falling speed will be always according to law of gravity but flowing speed may vary which depends on the source of it... Example for fall: water fall Example for flow: slower than water fall : river flow faster than water fall : water coming out of fire engine
The time it takes for a raindrop to reach the ground depends on its size and the height from which it falls. On average, a raindrop falling from a cloud about 1,000 meters high takes around 10-15 minutes to reach the ground.
Yes, a raindrop falling from the sky is considered to be in free fall because it is only under the influence of gravity with no other forces acting on it.
Air resistance, also known as drag force, acts on a raindrop as it falls to reduce its speed. This force increases as the raindrop's speed increases, eventually balancing out the force of gravity and causing the raindrop to fall at a constant speed.
i would aim for some one
"I'm just falling for you all!"
No it does not, as a raindrop falls to earth it will gradually slow due to the changing terminal velocity. As a raindrop falls, water will evaporate from it causing the mass to decrease faster than the size and surface area. this will leave the raindrop with a higher surface area to mass ratio. Since air resistance is related to surface area and mass, the smaller raindrop will have more air resistance for its mass and will fall slower.
yes
The average speed of a raindrop falling is around 8-10 miles per hour. However, this speed can vary depending on the size and shape of the raindrop.
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. Hope this helps.
Yes, drop sizes can affect the velocity of falling raindrops. Generally, smaller drops fall more slowly due to air resistance, while larger drops fall faster due to their mass overcoming air resistance. However, in reality, raindrop velocities are affected by various factors, including drop shape, density, and atmospheric conditions.
Depending on the size of the water droplets rain can fall anywhere from 5 to 18 MPH at sea level. Rain drops that would be large enough to fall faster than 18 MPH break up into smaller droplets once they reach this speed.
Depending on the size of the raindrop and the wind speed, updrafts, downdrafts a raindrop can fall at the speed of light. The previous answer was obviously written by an idiot. A raindrop will fall at usually 3 to 8 metres/second. A raindrop will never ever be able to travel at the speed of light.
