What happens to air resistance in a vacuum?

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.

How does a vacuum affect falling objects?

The mass, size, and shape of the object are not a factor in describing the motion of the object. So all objects, regardless of size or shape or weight, free fall with the same acceleration. In a vacuum, a beach ball falls at the same rate as an airliner.

Why do objects in a vacuum fall differently than objects falling in the air?

In a vacuum, gravity causes all objects to fall at the same rate. The mass of the object does not matter. If a person drops a hammer and a feather, air will make the feather fall more slowly. But if there were no air, they would fall at the same acceleration.

What happens if there is 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.

How does air resistance affect the acceleration of falling objects?

Air resistance increases with surface area, but also with velocity, because a higher velocity means an object is displacing a greater volume of air per second. When the acceleration due to gravity is balanced by the force of air resistance, the falling object reaches terminal velocity, and does not fall any faster.

What makes an object fall in a vacuum?

A vacuum chamber will suck out some air, creating less air resistance. The less air there is, the closer their rate of falling is! If you had no air at all, if you could truly get gravity to be the sole factor, then you could call the object being in free-fall, and you would prove Newton’s 2nd law true.

How can we make Gravity Fall in a vacuum?

To design a better experiment, we could try the same objects, but get rid of the air! We’ll use a vacuum chamber. A vacuum chamber will suck out some air, creating less air resistance. The less air there is, the closer their rate of falling is!

Can a vacuum chamber create less air resistance?

And of course, some objects are more affected by air resistance, like feathers. To design a better experiment, we could try the same objects, but get rid of the air! We’ll use a vacuum chamber. A vacuum chamber will suck out some air, creating less air resistance.
