What is the importance of air resistance?

With air resistance, acceleration throughout a fall gets less than gravity (g) because air resistance affects the movement of the falling object by slowing it down. How much it slows the object down depends on the surface area of the object and its speed.

Is there always air resistance on Earth?

With only the gravitational force, the object has a constant acceleration and the motion is fairly simple to model. However, objects on the surface of the Earth usually have an air resistance force on them also.

How is air resistance friction What would happen if there was no air resistance?

When an object is not moving there is no air resistance or friction present. However, in a vacuum tube where the air resistance is 0 (a vacuum reduces the density of the air to 0 which will reduce the force to 0) they will fall at the same rate.

What does it mean by no air resistance?

When an object falls with air resistance, both its acceleration and speed change during its motion. When an object falls in a vacuum, there is no air resistance because there is no air in a vacuum. A rock and a feather are released from rest from the same height with air resistance on.

How would it rain if there was no 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.

When there is no air resistance objects of different masses?

Objects that are said to be undergoing free fall, are not encountering a significant force of air resistance; they are falling under the sole influence of gravity. Under such conditions, all objects will fall with the same rate of acceleration, regardless of their mass.

Can air resistance be greater than gravity?

Air resistance is the name we give to the force that has to be used to push air out of the way. So it can never be greater than the force of gravity as it only exists because of the gravity acting on the object that is doing the pushing the air out of the way.

How would rain fall if there was no air resistance?

What is the meaning of no air resistance?

When an object falls with air resistance, both its acceleration and speed change during its motion. When an object falls in a vacuum, there is no air resistance because there is no air in a vacuum.

What is the acceleration without air resistance?

9.8 m/s2
It is also true that a free falling (no air resistance) object falls with an acceleration of 9.8 m/s2—but it’s still just the gravitational field. It doesn’t matter what object you put near the surface of the Earth, the gravitational field due to the Earth is constant and pointing towards the center of the Earth.
