Elasticity and Deformation Quiz

The ability of a body to change size and shape irreversibly

The ability of a body to permanently deform under stress

The ability of a body to resist a distorting influence and return to its original size and shape (correct)

The ability of a body to resist a distorting influence but not return to its original size and shape

Elasticity causes irreversible deformation, while plasticity allows the object to return to its original shape

Elasticity causes the object to permanently deform, while plasticity allows for temporary deformation

Elasticity allows the object to return to its original shape, while plasticity causes the object to remain in its deformed state (correct)

Elasticity and plasticity are essentially the same with no significant difference

Energy addition causing permanent deformation
