What is Pressure?

Pressure is a physical quantity that measures the force applied perpendicular to the surface of an object per unit area. It is a scalar quantity. It is measured in pascals (Pa) or pounds per square inch (psi). Pressure can cause deformation, compression, or expansion of materials.

Pressure Formula

Pressure formula relates the force applied perpendicular to the surface of an object to the area over which it is distributed. Mathematically, it is expressed as:

P = F/A

Where:

• P is the pressure exerted (measured in pascals, Pa),
• F is the force applied perpendicular to the surface (measured in newtons, N),
• A is the area over which the force is distributed (measured in square meters, m²).

Check, Types of Pressure

Force is a vector quantity, indicating both magnitude and direction, while pressure is a scalar quantity that considers magnitude only. Force represents the interaction between objects, causing motion or deformation, while pressure measures the force applied per unit area.

The main difference between force and pressure lies in their nature and application. In this article, we will learn the key difference between Force And Pressure in detail.
