Quick Answer: What happens to rain if there is no air resistance?

Contents

If there were no air resistance, then the speed of the drops would be very high. The impact of the drops would be very high, so it would be dangerous for us to go outdoors on rainy days.

Why does rain not fall all at once?

Originally Answered: Why doesn’t rain come down all at once? Rain results as a consequence of water vapor condensing either on a small portion of a drop of rain or on dust or salt in the cloud. This does not all happen at the same time so rain does not fall from everywhere in a cloud at the same time.

What happens when raindrops hit the ground?

A raindrop impacts a bare soil surface something like a metal ball striking the surface. The energy of the raindrop impact is transferred to the soil particles directly under the drop. If the kinetic energy of the drop is sufficient, soil particles are detached from the surface and fly out in all directions.

How much force does a raindrop have?

A stationary raindrop initially experiences an acceleration due to gravity of 9.8 m/s2, as would any falling body.

How long does it take for a rain drop to hit the ground?

Its difficult to give an exact figure as the height at which raindrops fall and their size vary widely, but given that raindrops fall at an average speed of around 14 mph and assuming a cloud base height of around 2,500 feet, a raindrop would take just over 2 minutes to reach the ground.

How does gravity affect rain?

While sunlight is the energy source, the greatest force propelling the water cycle is gravity. Gravity is the force of attraction between two objects, and Earth’s gravity pulls matter downward, toward its center. It pulls precipitation down from clouds and pulls water downhill.

How does the sky hold rain?

Just like tiny dust particles that float on the air, seemingly defying gravity as they dance in the light, these droplets hang suspended in the sky — for a time. … Eventually, the droplets in the clouds are heavy enough to be pulled down by gravity — and that’s rain!

What happens to a pond when it rains?

When a storm dumps a great deal of cold, dense water into your pond, it settles to the bottom, displacing the low-oxygen water at the bottom of the pond and causing it to turnover to the top of the pond where fish are typically found.

Can rain hurt you?

But studies do confirm that weather conditions can impact the body in various ways, including triggering a flare-up of past injuries. For some, the barometric pressure may affect arthritis of the joints, causing pain when the weather changes. For others, migraines occur more frequently in certain weather conditions.

What happens when a raindrop hits a puddle?

An initially still shallow puddle becomes curved at the surface after the raindrop hits. The surface force is different for long waves than for short ones, causing waves of different sizes to separate into ripples. … Imagine that rain is hitting a lake or ocean – or those deep pothole puddles that require galoshes.

How do the rain drops fall?

Gravity pulls everything downward. As an object falls, it experiences a frictional drag that counters the downward force of gravity. … You will not find a raindrop any bigger than about one-quarter of an inch in diameter; larger than that, the drop will break apart into smaller drops because of air resistance.

Do all the rain drops reach the Earth with the same speed?

It is impossible, in such a framework, to have drops of vastly different sizes moving at the same speed. However, large drops eventually break up, either because they become hydrodynamically unstable or as a result of temporary coalescence produced after a collision [Pruppacher and Klett, 1997].

What is the weight of raindrop?

Let us consider the average raindrop to have a radius of about 0.2 cm and a mass of about 0.034 grams.

Why does rain not hurt when falling?

The reason is called -Terminal velocity. This is a status of an object that stops to accelerate in free falling due to air friction and keeps its speed at the rate that other opposing forces allow.

What is it called when you can see rain falling in the distance?

In meteorology, a virga is an observable streak or shaft of precipitation falling from a cloud that evaporates or sublimates before reaching the ground.
