Inelastic Deformation - GCSE Physics Definition

Inelastic deformation refers to the permanent change in shape or size of a material when a force is applied and then removed. Unlike elastic deformation, where the material returns to its original form, inelastic deformation means the material has been altered beyond its elastic limit and cannot go back to its initial state. This occurs because the bonds between particles within the material are broken or rearranged. Understanding inelastic deformation is important in GCSE Physics as it helps explain how different materials respond to forces, especially in contexts like construction, engineering, and various physical phenomena.
