An Alternative Logic for Mass Defect

Although the mass of an object is defined to represent the equivalent of 3D matter it contains, it is often considered as the quantity of 3D matter contained in the object. Mass is the mathematical relation between an external linear effort on an object and the rate of the rate of its displacement in the direction of the external effort. This relationship is often ignored, and the value of a body's mass is regarded in almost all academic fields as the quantity of 3D matter present in the object. Loss (or gain) of mass of an object during its development stage or changes in its structure is understood as ‘mass defect’. This is often related to an assumed phenomenon of binding energy required to stabilize the nucleons in the atoms in a body.
