Force vs. Pressure: Know the Difference
By Shumaila Saeed || Published on January 29, 2024
Force is a push or pull acting on an object, while pressure is the force applied per unit area.
Key Differences
Force, in physics, refers to a push or pull exerted on an object, causing it to move or change its motion. Pressure, on the other hand, is a measure of force distribution over a specific area. While force directly influences the motion of an object, pressure describes how this force is spread across a surface.

The unit of force is the Newton (N) in the International System of Units (SI), where one Newton is the force needed to accelerate a one-kilogram mass by one meter per second squared. Pressure, however, is measured in Pascals (Pa), which equals one Newton per square meter. This distinction in units underscores the difference in their physical implications.

In practical applications, force can act in any direction and does not necessarily need a surface for its action. For instance, gravitational force acts on a body irrespective of any surface. Pressure, conversely, always requires a surface and is always perpendicular to that surface, as seen in the pressure exerted by gases or liquids in a container.

Different types of forces include gravitational, electromagnetic, and mechanical forces, each with unique characteristics. Pressure types, such as atmospheric, hydraulic, and osmotic pressure, vary based on the medium and circumstances, demonstrating their distinct nature from force.

While force is fundamental to Newton's laws of motion, directly affecting an object's dynamics, pressure relates more to thermodynamic and fluid dynamic principles, impacting states of matter and phase transitions. Their interaction with other physical concepts further delineates their unique roles.
