Elasticity is the ability of an object or substance to return quickly to its original shape and size after being bent‚ stretched‚ or squashed. When an elastic material is deformed due to an external force‚ it experiences internal forces that oppose the deformation and restore it to its original state if the external force is no longer applied. There are various elastic moduli‚ such as Young’s modulus‚ the shear modulus‚ and the bulk modulus‚ all of which are measures of the inherent stiffness of
