Elasticity
The mechanical property of a material to deform under applied stress and return to its original shape when stress is removed.
Governing formula
Stress / Strain = Elastic Modulus (E)
SI unit
Pa (N/m²)
In depth
Within the elastic limit, deformation is temporary and reversible. Beyond the yield point, permanent plastic deformation occurs.
Examples in the real world
A rubber band stretching under tension and snapping back to its original length.
