elastic materials

Elastic materials are substances that can deform when a force is applied, such as stretching or compressing, but return to their original shape once the force is removed. This ability to stretch and then recover is called elasticity. Common examples include rubber bands, springs, and certain metals. The key characteristic is that they store energy when deformed and release it when returning to their original form. Elasticity is important in many engineering and everyday applications, ensuring materials can absorb shocks, return to shape, or flex without permanent damage.
