[/quote] "On average, a column of air one square centimeter in cross-section, measured from sea level to the top of the atmosphere, has a mass of about 1.03 kg and weight of about 10.1 N." http://en.wikipedia.org/wiki/Atmospheric_pressure This matches air pressure just fine. If you can't do the measurements and calculate the numbers all you can ever do is [i]guess[/i]. :book: [/quote] A column of air one square meter is said to weigh over 100,000 Newtons or 10.2 metric tons.. Air pressure is a force in all directions.. gravity is a force pressing down.. atmosphere is gas, not air pressure. We must be supermen to resist this weight.. [/quote] The secret ingredient is the fact that we're mostly liquids. You seem to be rather confuddled about what it is that causes air pressure. :book: [/quote] Air pressure is not weight... it's pressure.. See aneroid barometer.. The effects of gravity on atmosphere at sea level is basically zero. No weight is measured on a scale. What is holding up the mass of atmospheric gas..? You are saying that the weight of the gas is not effectively measurable on a scale because we are liquid..? [/quote]
How does gravity works? I like to know what causes these forces.
Any specialist on this subject here?
