Pressure is the force applied per unit area on a surface, influencing fluid dynamics and mechanical systems.

• Pressure is measured in units such as Pascals (Pa), atmospheres (atm), or pounds per square inch (psi).

• In fluids, pressure increases with depth due to the weight of the fluid above.

• Example: Atmospheric pressure at sea level is approximately 101.3 kPa.

• In medical terms, blood pressure is a critical measure of cardi
