No. Quite on the contrary: Air provides a buoyant force, that will partially counteract the force of gravity. And if the object has a low density (as in a balloon), it may even get the object from the ground.
Yes, atmospheric pressure can affect an object's velocity. Higher atmospheric pressure can create more air resistance, which can slow down the object. Conversely, lower atmospheric pressure can result in less air resistance, allowing the object to move faster.
The atmospheric pressure plays a huge role when determining the weather. If the pressure is high, winds will be more active.
Normal atmospheric pressure is abbreviated as atm. But when computing for the amount of total pressure exerted on an object at a specific depth or elevation, including normal atmospheric pressure, then the abbreviation ata is used. It stands for atmospheric pressure absolute.
When the water level is higher inside the flask than outside, the gas pressure in the flask would be lower than the atmospheric pressure. This is because the water exerts a partial vacuum on the gas in the flask, reducing its pressure compared to the external atmospheric pressure.
The force of colliding particles
Air pressure and atmospheric pressure are the same things, just called differently. It refers to the weight of air being exerted on an object.
it depends on the area
Ground pressure can be increased by either adding weight to the object exerting pressure or by reducing the surface area in contact with the ground. Increasing the weight or decreasing the area will concentrate the force, leading to higher ground pressure.
Atmospheric pressure is the pressure exerted by the weight of the atmosphere above a given point, while water pressure is the force exerted by water on an object or surface due to the depth of the water. Atmospheric pressure decreases with altitude, while water pressure increases with depth.
The opposite of barometer is likely to be an object that does not measure atmospheric pressure, like a clock or a thermometer.
The pressure exerted by an object is determined by its weight and the area over which the weight is distributed. A lighter object can exert more pressure towards the ground if it has a smaller contact area with the ground, concentrating the force into a smaller area. In contrast, a heavier object with a larger contact area would distribute its weight over a wider area, resulting in less pressure per unit area.
To reduce the pressure an object exerts on the ground, you can increase the area over which the force is distributed. This can be done by using wider supports or distributing the weight of the object over a larger surface area. Another way is to decrease the force being applied to the object itself.
