Question: What does air resistance do to rain?

Contents

What would happen if rain didn’t have air resistance?

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.

What forces are acting on rain?

The diagram below shows two of the forces acting on a falling particle of rain. Gravity pushes it down while air resistance slows the motion. Note that air resistance will not accelerate the raindrop upward but it can slow the downward motion. Thus, air resistance increases as falling motion increases.

Which force is involved in falling of raindrops?

Gravity accelerates all objects towards the ground at a specific rate. Without any other forces present, the speed of an object in free fall will increase the farther or longer it falls. However, air friction or air resistance also exerts a force on an object (raindrop) that opposes the weight force of gravity.

Why does rain not fall all at once?

The combination of high cloud bases and dry air mean that storms rarely send much rain to the ground. … But when they happen, it’s as if an entire cloud full of water condenses all at once and drops from the sky.

How does the force of gravity on a raindrop?

Because the drop is moving at constant velocity the net force acting on the raindrop is 0N. Therefore the force of gravity, say XN, pulling the drop downward is canceled out by the force of the air pressing onto the raindrop. So this force will be equal and opposite to the force of gravity, -XN.

Why does a falling raindrop not accelerate?

When you drop something in air, it does not accelerate forever. … This is known as air resistance or drag. As the object gains velocity there comes a time when the force of the air resistance is enough to balance the force of gravity, so the acceleration stops and the raindrop attains terminal velocity.

Why do raindrops fall with constant velocity?

Rain drop falls with a constant velocity because the weight(which is the force of gravity acting on body) of the drop is balanced by the sum of the buoyant force and force due to friction(or viscosity )of air. Thus the net force on the drop is zero so it falls down with a constant velocity.

Is the weight of an object the same as its mass?

We often use the words ‘mass’ and ‘weight’ interchangeably, but they mean quite different things. Your mass is the same no matter where you go in the universe; your weight, on the other hand, changes from place to place. … Mass is a measure of how much force it will take to change that path.

Which of the following force is responsible for the raindrops falling down words?

Water droplets in clouds which eventually form rain have mass. Therefore, they are pulled towards the Earth by the gravitational force of Earth.

Why do the drops of rain fall with monotonous movement?

The force due to air resistance increases with the speed of the rain drops until it balances the gravitational force.
