What is Hook's law?

Deformation is not fully reversed when the force is removed - there is a permanent change in shape.

It states that  within the elastic limit, extension is directly proportional to load applied to it, provide the  limit of proportionality is not exceeded.

Deformation is reversed when the force is removed.

Point beyond which the spring will no longer return to its original shape when the force is removed.
