👉 Pressure, often denoted as \( P \), is a measure of force applied per unit area and is a fundamental concept in physics, particularly in fluid dynamics. Mathematically, it's defined as \( P = \frac{F}{A} \), where \( F \) is the force applied and \( A \) is the area over which that force is distributed. This relationship shows that pressure is directly proportional to the force and inversely proportional to the area. For example, if you compress a gas in a container, the pressure increases because the same force \( F \) is now applied over a smaller area \( A \). This principle is crucial in understanding phenomena like hydraulic systems, where a small force applied to a small area can generate a much larger force over a larger area, enabling powerful machinery and vehicles.
