grandezza fisica intensiva

AI overview

Pressure is the force pushing down on a surface, spread out over an area—think of how your weight distributes across your feet versus across the tip of a needle. Understanding pressure matters because it helps explain everyday phenomena, from why sharp objects pierce easily to how air and liquids behave in different situations.

La pressione è una grandezza fisica, definita come il rapporto tra il modulo della forza agente ortogonalmente su una superficie e la sua area. I fluidi subiscono soltanto l'effetto della pressione (legge di Pascal), mentre i solidi risentono più generalmente quello della tensione. La pressione, come la tensione, rientra nel concetto di sollecitazione.
