Explain the properties of elasticity.
Elasticity is the property of recovery of an original size or shape of matter exposed to a force. Something is considered "more elastic" if it restores itself more precisely to its original configuration. The property's namesake, the "elastic" or rubber band, has a high degree of elasticity but can be permanently deformed if too much force is applied in stretching. This property allows the study of the "strength of materials," and compressibility, and is usually described through the Bulk Modulus formula (to determine the amount of deformation and reformation) and Young's Modulus (to determine the amount of elongation and contraction)
