What is elasticity?
What is elasticity?
If an external force is applied to an object and it changes or tries to change the shape and size of the object, the property of the object that obstructs this tendency of deformation, and if the force is taken away the object regains its original size and shape is elasticity. Those objects that have this property are known as elastic bodies.
or,
When force is applied on an object, a deformation happens inside it (and for this deformation, a counter force is created). If the force is withdrawn, deformation stops and the object comes back to its initial condition. This property of a substance is known as elasticity.
