Theoretically, if there is no (negligible) gravity in a specific area, there will be no atmosphere (outer space is a good example).

So, theoretically......there would be no air resistance.

There can be oxygen with no gravity! For example, lets take a spaceship and fill it with oxygen, with no air holes so the oxygen wont escape. But every time you inhale, your lowering the amount of oxygen you have, so you might want to take a couple of plants. The plants will inhale your carbon dioxide (CO2) and exhale more oxygen for you to inhale.

Yes, gravitation is a force, while air is a fluid. It would feel is if there was a lot less gravity though, as there would be a decrease in air pressure, and air resistance, making movement easier.

Gravity has a constant acceleration value (9.8m/s^2) and acts downward always. Air resistance is as its name suggests a force that only acts when an object is moving, and it can act in any direction (always opposite the direction of motion).

a moving object would only stop if it met an obstruction and it would not slow down if it was in the air

How does air effect gravity?

Air has no effect on gravity. But the presence of air can change the response of an object to the force of gravity alone.


Does air pressure affect gravity?

Gravity is a function of mass and distance. So, no air pressure does not affect gravity.


Doea gravity affect the air that we breath in?

Yes. Without gravity, we would have NO air to breathe.


How does the earth's gravity hold air around the planet?

Air has mass, and gravity pulls anything with mass. The gravity of the earth "pulls" air down towards it's center.


Does gravity affect the air we breathe?

Yes, gravity affects the air that we breathe. That is why it is harder to breathe when we go up high mountains. There is less air there. Without gravity, the air would float off into space, just as we would.


What force is stronger gravity or air resistance?

Gravity is stronger. If gravity was not stronger air would make us float away. Air is trying to make things go up and gravity is making things go down.


Why does Air stay within the Atmosphere - solid and liquid are pulled by gravity BUT i don't agree Air is pulled by gravity?

First of all, the atmosphere is the air. Secondly, air is matter, all matter is affected by gravity. Imagine this: the sea is liquid, it lies on the earth, pulled by gravity. the atmosphere is also like this except it is a "sea" of air, it lies on the earth, pulled by gravity.


Is it the air pressure that keeps us on the ground or is it gravity?

It is gravity.

It does not.

The sky is air and gravity keeps the air close to the ground so we can breeth it in .


How is gravity used in gymnastics?

Gravity is not "used". In gymnastics, gymnasts almost defy-gravity by flipping in the air but have no control of what gravity does.
