Force vs. Pressure: What's the Difference?
Edited by Huma Saeed || By Sumera Saeed || Updated on October 25, 2023
Force is a push or pull acting on an object, while pressure is the force applied per unit area.
Key Differences
Force and pressure are fundamental concepts in physics, often misunderstood as interchangeable. Force, by its definition, refers to any interaction that changes the motion of an object. It can either push it, pull it, or cause some form of movement or deformation.

On the other hand, pressure describes how force is distributed over a specific area. While force can be direct and tangible, pressure gives a more concentrated picture, illustrating how much force is acting on each unit area of a surface.

It’s also important to recognize the units in which both are measured. Force is typically measured in Newtons (N) in the International System of Units. Pressure, because it’s force per unit area, is usually measured in Pascals (Pa), which translates to one Newton per square meter (N/m²).

Another distinguishing factor between force and pressure is their application in real-life scenarios. For instance, when you push a wall, you exert force. However, when you press the sharp end of a nail against a surface, the area over which the force is applied is small, leading to high pressure.
