Considering the rain droplets as spherical body. We have two forces acting on the rain drop when it is falling through the sky, namely the resistance force due to friction(drag force)upwards and its weight downwards. Th rain drop falling from such distance attain a terminal velocity while falling i.e their speed becomes constant after sometime. This happens when the drag force equals the weight of drop,, this happens because drag force increases with velocity of the drop.
Drag force= .5*rho*v2*A(frontal area)*Cd(coefficient of drag)
Weight=m*g=rho*volume of spherical drop=rho*4/3*r3.
When we equalize it,
we get the Terminal Velocity(v) varying directly as sqr of r(radius of drop)
So larger drop means, larger terminal velocity and hence less time taken for falling.
So larger rain drop falls faster.
What else can I help you with?
Which fall faster big rain drop or small rain drop?
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.
What is the highest one drop falls in the world?
The highest one-drop waterfall in the world is Angel Falls in Venezuela, which has a total height of 3,212 feet (979 meters) and a continuous drop of 2,648 feet (807 meters).
Why is air resistance a frictional force?
If you drop an elephant and an equal weight amount of feathers, the elephant will hit the ground first. The elephant falls faster than the feather because it never reaches a terminal velocity; it continues to accelerate as it falls accumulating more and more air resistance.
How does a drop of water get its shape?
If the drop is small enough, it is a perfect sphere. A sphere is the geometrical shape that has the smallest surface area for its volume. The drop takes this shape because water molecules are pulling inward toward each other, and tend to stick to each other. So when not confined by a container and with nothing around it to distort its shape a very tiny water drop is perfectly round like a ball. If the drop is larger like a raindrop, it has domed top and semi- flattened bottom because as it falls, it must push the air out of its way. It is that upward push of the air being displaced that causes the falling drop to have a rather flattened bottom, so that it looks like a tear drop. the bits of water piles up. this makes the dome shapes
What waterfall has the longest drop of any in the world and where is it located?
The highest waterfall in the world is Salto Angel Falls on the Rio Gauja in Venezuela at 979 metres.
What is drop a dingy?
a dingy is a small rowboat. You drop it over the side of a dock or of a larger boat.
Why does the veins of a leaf appear larger when a dew drop falls on it?
THe water droplet acts as a magnifying lens.
Is it true that the higher you drop something from the faster?
Yes, as an object falls, it accelerates due to gravity. This means that the longer it falls, the faster it gets until it reaches its terminal velocity, the maximum speed at which it can fall in a specific medium like air or water.
Are the Huka Falls over 50 meters tall?
The falls have two stages. 8 meters in small waterfalls and a large 11 meter drop.
What is a dingis?
a dingy is a small rowboat. You drop it over the side of a dock or of a larger boat.

Is the highest waterfall in the US located at Yosemite National Park?
Yosemite Falls in California has a drop of 2,425 feet. Colonial Creek Falls in Washington has a drop of 2,584 feet. Waihilau Falls on the big island of Hawaii has a drop of 2,600 feet. Pu'uka'oku Falls in Hawaii has a drop of 2,756 feet. Olo'upena Falls on Molokai Hawaii has a drop of 2,953 feet. Angel Falls in Venezuela holds the world record at 3.212 feet.
Why a hammer falls faster than a feather if you drop them on earth?
A hammer falls faster than a feather when dropped on Earth because of gravity. Gravity pulls objects with mass towards the Earth at a constant rate of acceleration, regardless of their size or shape. Since the feather has more surface area and air resistance, it falls slower than the hammer, which is more dense and streamlined.
What is the name of the famous falls found in New York?

Treman State Park Taughannock Falls - 66 m (215 ft) single, vertical drop, flowing year-round VerKeerderkill Falls - 54.6 m (180 ft) sheer drop Buttermilk Falls, located in Buttermilk Falls State Park
What is the meaning of dropped?
of Drop, The action of causing to drop or of letting drop; falling., That which falls in drops; the excrement or dung of animals.
How high are the Della Falls in British Columbia?
the falls are a vertical drop of about 440 meters.
Why water forms large drops as it falls from a faucet with a slow leak?
the water must reach a certain mass weight in order to release the faucet surface and fall, therefore with a slow leak the drop can form a larger drop before falling.
