Pressure

Pressure is the force applied perpendicular to the surface of an object per unit area. It is a fundamental concept in physics and has many practical applications in everyday life.

Factors Affecting Pressure

• Force: The amount of force applied to an area affects the pressure. The greater the force, the higher the pressure.
• Area: The size of the area over which the force is applied also affects pressure. Smaller areas experience higher pressure for the same force.

Units of Pressure

Pressure is typically measured in pascals (Pa) or other units such as atmospheres (atm) or millimeters of mercury (mmHg).

Applications of Pressure

Pressure has numerous applications in various fields, including:

• Hydraulics and pneumatics
• Weather systems and meteorology
• Medical devices like blood pressure monitors
• Scuba diving and underwater exploration
