Pressure
Pressure is a fundamental physical quantity that plays a crucial role in various phenomena across the natural world. Defined as the force exerted per unit area, pressure manifests in countless contexts, from atmospheric pressure influencing weather patterns to the pressure within cells regulating biological processes. Understanding pressure is essential in fields as diverse as physics, engineering, and medicine, where it governs fluid dynamics, structural integrity, and physiological functions. Exploring its properties and effects enables insights into complex systems and drives innovations in technology and science.
