In physics, this term refers to the application of inward forces to an object or substance, resulting in a reduction in its volume. This phenomenon is characterized by an increase in density and pressure within the material. A common illustration involves squeezing a sponge; the applied pressure diminishes its size while simultaneously increasing its density.
This process is fundamental across various scientific and engineering disciplines. It plays a crucial role in understanding the behavior of materials under stress, influencing the design of structures, engines, and various mechanical systems. Historically, the study of this concept has led to advancements in material science, enabling the creation of stronger and more resilient materials capable of withstanding significant forces.
