Elasticity - GCSE Physics Definition

Reviewed by: Philippa Platt

Published

Elasticity in physics refers to the property of a material that enables it to return to its original shape and size after it has been stretched, compressed, or otherwise deformed by an external force. It describes how materials like rubber bands and springs can regain their initial form once the force is removed.

The concept of elasticity is quantified by Hooke's Law, which states that the force needed to change the shape of an elastic object is directly proportional to the amount of deformation, as long as it does not exceed the material's elastic limit. Understanding elasticity is crucial for predicting how different materials will respond under various mechanical stresses.
