Deformation - GCSE Physics Definition

Reviewed by: Philippa Platt

Published

Deformation in the context of GCSE Physics refers to a change in the shape or size of an object due to an applied force. When forces such as tension, compression, bending, or torsion act on a material, it may undergo deformation, which can be either elastic or plastic.

Elastic deformation is reversible, meaning the object returns to its original shape once the force is removed. In contrast, plastic deformation is permanent, as the object retains its new shape even after the force is no longer applied.

Understanding deformation is essential for studying the behaviour of materials under different physical conditions, and it plays a crucial role in areas like material science and engineering.
