Compression - GCSE Physics Definition

Reviewed by: Philippa Platt

Published

Compression, in the context of GCSE Physics, refers to the process by which an object or substance is reduced in volume as a result of applied pressure. It involves the particles within a material being forced closer together, thereby increasing the material's density.

This phenomenon is a key concept in understanding sound waves in gases, where areas of compression alternate with areas of rarefaction to propagate sound.

Additionally, it is important when studying the behaviour of materials under different forces, such as in examining how springs and other elastic materials deform when compressed.
