PPT-Measuring air pressure Modern Barometers

Earths gravitational force Atmospheric Pressure As the atmosphere is held down by gravity it exerts a force upon every surface pressure force per unit area At sea level the force is the weight of 1 kg of air that lies above each square centimeter of the surface around 15 lbs per in.
