Here's why:

* Pressure is defined as force applied over a specific area.

* Compression involves applying force to an object, causing it to shrink in volume.

* Therefore, the pressure applied during compression directly relates to the force being used to compress the object.

Units of Pressure:

* Pascal (Pa): The standard unit of pressure in the International System of Units (SI).

* Pound per square inch (psi): Commonly used in the United States.

* Bar: Another unit often used in pressure measurements.

Example:

Imagine squeezing a spring. The harder you squeeze (the more force you apply), the higher the pressure you create within the spring. This higher pressure corresponds to a greater force of compression.
