Final answer:
The statement is false; deformations can be elastic, allowing an object to return to its original shape after the force is removed. This follows Hooke's law for small deformations.
Step-by-step explanation:
The statement 'When an object deforms, the change of shape is always permanent' is false. In the field of physics, when a force causes an object to change shape, this is called deformation. Deformations can be elastic or plastic. For elastic deformations, the object will return to its original shape once the applied force is removed. This behavior is described by Hooke's law, which states that the size of the deformation is proportional to the applied force for small deformations. However, if the deformation is plastic, then the change in shape will be permanent. Therefore, not all deformations are permanent.
