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.

Why a larger rain drop falls faster than a small rain drop?

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.


Clouds are very high in the sky but the rain-drops falling from the clouds havelow velocities as they reach the ground.?

the reason why is because of the shape and weight if the rain drop. the weight of a rain drop is less than a gram and the shape of one when falling from the sky, has a lot of drag. this means that the terminal velocity of a rain drop is very slow


What falls faster rain or snow from the sky?

Rain falls faster than snow from the sky because raindrops are larger and heavier than snowflakes, allowing them to fall at a quicker rate. Snowflakes are lighter and can be easily slowed down or carried by wind currents.

How might a period of very heavy rain cause a flood to occur?

A period of heavy rain can drop rain on an area faster than drainage systems and streams can carry it away.

What does rain and a pillow have in common?

Both rain and a pillow fall when you drop them, the susceptibility to gravity is something that almost all things have in common, though. Rain falls and a pillow is for falling asleep.


What is a light fall of rain?

A light fall of rain refers to a gentle and typically brief shower of rain. It is characterized by small, widely spaced raindrops that are not heavy enough to cause significant disruption or accumulation.
