What is pressure in physics?
Quick Answer
Pressure is force applied per unit area. It is measured in pascals.
The Full Story
Pressure tells you how concentrated a force is over a surface. The SI unit is the pascal, equal to one newton per square meter. In gases and fluids, pressure is extremely important because it controls weather, buoyancy, and fluid flow. Atmospheric pressure at sea level is about 101,325 pascals, or 1 atmosphere. Pressure also matters in engineering, from hydraulic systems to deep-sea submarines.
