👉 Stretchiness, also known as elasticity or rigidity, is a characteristic of materials that allows them to deform in response to external forces. It's a property that depends on the material composition and its mechanical properties like density, stiffness, and plasticity. The term "stretchiness" can be used when referring to the ability of a material to change shape under an applied force or load. This means that a material will not only deform in response to external forces but also exhibit a certain level of flexibility
