In physics, elasticity refers to the property of a material to deform when a force is applied and then return to its original shape when the force is removed. This behavior is observed in various materials, such as rubber bands, metals, and many other elastic substances. The fundamental concept of elasticity can be defined using Hooke's Law, which states that the strain (deformation) in a solid material is directly proportional to the applied stress (force) within the elastic limit of that material.
