Force Per: Unit Area

Pressure differences above and below airplane wings create the lift necessary for flight.

. It is a scalar quantity measured in in the SI system. force per unit area

): A scalar quantity representing the magnitude of force per unit area. Force ( Pressure differences above and below airplane wings create

If force is constant, increasing the area decreases the pressure. This explains why a heavy elephant exerts less pressure on the ground than a person in high heels. 4. Real-World Applications force per unit area

Based on the average air pressure at sea level ( Bar: Often used in meteorology and engineering (

Dam bases are built thicker at the bottom to withstand higher water pressure at greater depths.

P=FAcap P equals the fraction with numerator cap F and denominator cap A end-fraction Pressure (
