Air does have a weight! And it is because of gravity! Note that this is per definition true because weight is only defined in the presence of gravity.
Perhaps you are confused about why the air is up in the atmosphere and not down here on the ground with us?
This has to do with air pressure. You see, materials don't like to be compressed, which is what gravity tries to do. Gravity tries to compress the air to the ground, but faces increased air pressure as it does so.
Basically what happens is that the air particles repulse each other and thus tend to drive them apart. This force increases if you force the particles to be closer to each other.
As gravity tries to pull air down, the air pressure increases which counter balances the pull of gravity. In the end a stable system is formed where the air pressure is highest down near the ground and lowest up in the upper lays of the atmosphere.
The air particles up in the atmosphere do feel gravity, but if they would move down they would feel an increased air pressure which pushes them up again!
What else can I help you with?
Is air pressure a result of gravity?
Yes, air pressure is a result of gravity. The weight of the air molecules above a specific area creates pressure at that point. Gravity pulls the air molecules towards the Earth's surface, causing them to be compressed and create pressure.
How do you calculate weight using specific gravity?
To calculate weight using specific gravity, you multiply the specific gravity of the substance by the weight of the substance in air. This gives you the weight of the substance in a vacuum.
How much does an object weigh in air?
An object's weight in air is the same as its weight in a vacuum. This is because weight measures the force of gravity acting on an object, and gravity affects objects in air and in vacuum in the same way.
Does weight disappear if the air disappears?
No, weight is a measure of the force due to gravity acting on an object. Even if air disappears, the force of gravity will still act on the object, so its weight will not disappear.
What is a force that can change when acceleration due to gravity changes?
Weight. The force of weight experienced by an object can change when the acceleration due to gravity changes. Weight is directly proportional to the acceleration due to gravity, so an increase or decrease in gravity will result in a corresponding change in weight.
Is weight the result of air pressure exerted on an object?
Mass and Earth's gravity
Is air pressure a result of gravity?
Yes, air pressure is a result of gravity. The weight of the air molecules above a specific area creates pressure at that point. Gravity pulls the air molecules towards the Earth's surface, causing them to be compressed and create pressure.
Weight is the result of air pressure exerted upon an object?
Weight is the force of gravity acting on an object's mass, not air pressure. Air pressure is the force exerted by the atmosphere on objects. Weight depends on the mass of the object and the acceleration due to gravity, while air pressure depends on the density of air and the height above sea level.
What is the result of air mass?
the result of air mass/air weight is air pressure.
Does gravity give air weight?
Yes.
How do you calculate weight using specific gravity?
To calculate weight using specific gravity, you multiply the specific gravity of the substance by the weight of the substance in air. This gives you the weight of the substance in a vacuum.
How much does an object weigh in air?
An object's weight in air is the same as its weight in a vacuum. This is because weight measures the force of gravity acting on an object, and gravity affects objects in air and in vacuum in the same way.
Is there such thing as weight?
Yes. Weight is the vertical force exerted by a mass as a result of gravity.
Can a object have weight without having mass?
No. Weight is the result of gravity acting on mass.
Does weight disappear if the air disappears?
No, weight is a measure of the force due to gravity acting on an object. Even if air disappears, the force of gravity will still act on the object, so its weight will not disappear.
What is a force that can change when acceleration due to gravity changes?
Weight. The force of weight experienced by an object can change when the acceleration due to gravity changes. Weight is directly proportional to the acceleration due to gravity, so an increase or decrease in gravity will result in a corresponding change in weight.
How is weight related to the force of gravity?
Weight is the result of the force of gravity acting on an object's mass. The greater an object's mass, the stronger the force of gravity pulling on it, resulting in a higher weight. Weight is directly proportional to the mass of an object under the influence of gravity.
