A body is said to be perfectly elastic if

A body is said to be perfectly elastic if it recovers its original shape/size when the deforming force is removed.


Elasticity is the property of a body to regain its original shape and size when deforming forces are removed. It exhibits an opposition to change. Elasticity is the ability of a body to resist any permanent changes to it when stress is applied.

Key points

  • All materials have an elastic limit beyond which, if continuous stress is applied, they will start losing their ability to exhibit perfect elastic behaviour and start deforming.
  • When an external force is applied to a rigid body there is a change in its length, volume (or) shape.
