## Class 11 Physics, Chapter – 12, Elasticity

Class – 11, Chapter – 12, Elasticity Introduction :  In our daily life, there are some objects whose shapes, volume and length may be changed permanently or temporarily by applying external force. After removal of the applied force, the objects may recover completely or partially its original shape, volume and length.  Read more…
