What property describes the ability of a strained object to return to its original shape after deformation?

• A. Elasticity
• B. Density
• C. Acoustics
• D. Interference

Answer: (A)

Elasticity is the property that lets a material recover its original shape after being deformed when the applied force is removed. When you stretch or compress a solid within its elastic limit, the internal bonds and structure store energy momentarily, and once the load is released, they return to their original arrangement, restoring shape. If you push beyond that limit, the material may deform permanently (plastic deformation) and won’t fully recover. For context, density describes mass per volume, acoustics deals with sound, and interference concerns how waves interact. In this case, elasticity best explains the material’s return to its initial form after deformation.
