A material is said to be elastic if it:

Step 1: Understand what 'elastic' means. It refers to the ability of a material to stretch or compress.
Step 2: Learn about 'stress'. Stress is the force applied to a material that causes it to change shape.
Step 3: Know what happens when stress is applied to an elastic material. It changes shape (stretches or compresses).
Step 4: Remember the key point: after the stress is removed, an elastic material goes back to its original shape.
Step 5: Conclude that if a material can return to its original shape after stress is removed, it is elastic.

Elasticity – Elasticity refers to the ability of a material to return to its original shape after the stress causing deformation is removed.
