Air pressure is a measure of the force of per square unit exerted on the surface of an object, and is fairly straightforward to calculate: Pressure = Force/Area. This force is directly proportional to the temperature and density of the gas (increasing either increases the force applied). Air pressure is the same on all sides of an object, and produces no net force on the object.
Air resistance is the force applied by a gas to an object moving in the gas. This force is in the direction opposite of the object's motion, and is caused by the object being bombarded by gas molecules as it moves.
One way to think about it is that each molecule of gas the object comes into contact with must be displaced if the object is to continue moving. It requires energy to move the mass of the gas molecule. This energy comes from the moving object, which transfers a very minute portion of it's momentum to the gas molecule. Even though molecules are extremely small and light, these collisions add up on a large scale, since there are over a billion, billion, billion air molecules per cubic centimeter. Calculating air resistance is much more involved than calculating air pressure, involving some advanced mathematical concepts. It is, however, partially dependent on air pressure.
In short, increased air pressure increases air resistance for a moving object, but the two concepts are not the same.
Isobars are lines on a map joining places that have the same atmospheric pressure.
The air pressure at the top of our heads is the same as the air pressure at any other point at the same elevation above sea level. The air pressure decreases with increasing altitude due to the weight of the air above pushing down on the air below, creating the atmospheric pressure we experience.
The atmospheric pressure plays a huge role when determining the weather. If the pressure is high, winds will be more active.
Atmospheric pressure is the weight of the air above the point... at sea level there is more air above the point then there would be at 10,000ft
Atmospheric pressure decreases with height due to the weight of the air above pushing down on the air below. As you move higher in the atmosphere, the air becomes less dense because there is less weight of air above it, leading to a decrease in pressure.
Atmospheric Pressure means the same. It is a synonym for air pressure.
Atmospheric pressure is another name for air pressure. This is because the atmosphere is pretty much the same as air.
Yes, barometric pressure is the same as atmospheric pressure. Both terms refer to the pressure exerted by the weight of the air in the Earth's atmosphere.
Air pressure and atmospheric pressure are the same things, just called differently. It refers to the weight of air being exerted on an object.
Barometric pressure refers specifically to the pressure exerted by the atmosphere, while atmospheric pressure is the force per unit area exerted against a surface by the weight of the air above that surface. In essence, barometric pressure is a type of atmospheric pressure.
Atmospheric pressure systems are made of air.
Isobars are lines on a map joining places that have the same atmospheric pressure.
The air pressure at the top of our heads is the same as the air pressure at any other point at the same elevation above sea level. The air pressure decreases with increasing altitude due to the weight of the air above pushing down on the air below, creating the atmospheric pressure we experience.
Yes, the weight of the air exerts pressure on the Earth's surface, creating atmospheric pressure. This pressure decreases with altitude as the air becomes less dense.
Atmospheric pressure is the weight of the air.
Atmospheric pressure is the weight of the air or the pressure exerted onto the Earth by the air. Pressure changes can lead to different weather patterns.
an air compressor Or gravity if you mean atmospheric pressure.
