Why water become thinner when falling?

In summary, when water falls, its speed increases due to gravity while the volumetric flow rate remains constant. This can cause the water to separate into droplets due to surface tension.

Because it becomes faster whereas the volumetric flow rate remains constant.

thanks but,
why volumetric flow rate is constant?

"Volumetric flow" is the amount of water coming out of the faucet in a given time. That does not change. But as the water falls, its acceleration is, of course, g so that its speed is constantly increasing.

if water fall from a large height what happen?(molecules very close to each other)

You can see it in your sink or a waterfall: the water separates into droplets due to surface tension.

1. Why does water become thinner when falling?

Water becomes thinner when falling due to the force of gravity. As the water falls, it experiences a downward force that causes it to spread out and become thinner.

2. Does temperature play a role in water becoming thinner when falling?

Yes, temperature can play a role in water becoming thinner when falling. When water is heated, the molecules move more quickly and spread out, making the water less dense. This lower density can cause the water to become thinner when falling.

3. How does air resistance affect water when it falls?

Air resistance can affect water when it falls by slowing down its descent. As water falls, it collides with air molecules, which creates drag and causes the water to spread out and become thinner.

4. Is the shape of the water droplet important in determining its thickness when falling?

Yes, the shape of the water droplet can impact its thickness when falling. A smooth, round droplet will experience less air resistance and therefore stay thicker for longer, while a more irregularly shaped droplet may break apart and become thinner quicker.

5. Can other factors, such as pressure, affect the thinning of water when falling?

Yes, pressure can also play a role in the thinning of water when falling. As water falls from a higher altitude to a lower altitude, the air pressure increases, which can cause the water to become thinner as it falls due to the increased resistance from the air molecules.
