Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure (also spelled gage pressure) is the pressure relative to the ambient pressure.
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.
