Explanation:
Detailed explanation-1: -elasticity, ability of a deformed material body to return to its original shape and size when the forces causing the deformation are removed. A body with this ability is said to behave (or respond) elastically.
Detailed explanation-2: -The ability of a material to regain its original shape, after it has been stretched or compressed is called elasticity.
Detailed explanation-3: -When energy goes into changing the shape of some material and it stays changed, that is said to be plastic deformation. When the material goes back to its original form, that’s elastic deformation. Mechanical energy is lost whenever an object undergoes plastic deformation.
