What is atmospheric pressure in your own words?
The air around you has weight, and it presses against everything it touches. That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth. Atmospheric pressure is commonly measured with a barometer.
What is the atmospheric pressure on a person?
The average human body surface area is 1.73 m2 and the standard atmospheric pressure is 101,325 N/m2. Hence the total atmospheric force exerted on the average human body would be 1.73 m2 x 101,325 N/m2 = 175,300 N (approx.).
What is a sentence for atmospheric pressure?
