Will the quality of the spring become heavier after compression?

In the future, at the level of "conservation of mass and energy", the spring will definitely become heavier and meet the potential energy Ek for spring progress (or stretching)=Ek=Δmc^2, such changes alone are very subtle. The mass energy equation states that any change in the energy of a closed system will result in a change in the relativistic mass, in order to satisfy the conservation of mass and energy.

At the microscopic level of compression (stretching) of spring: it is the increase in molecular potential energy between spring molecules. Assuming that the Compression Spring is made of iron, that is, the uniform distance between iron atoms decreases (increases), and the energy input from the outside is converted into potential energy between iron atoms. This will inevitably lead to an increase in the relative mass of iron atoms with further potential energy, resulting in an overall improvement in the relative mass of the spring. This will slightly overturn the high school law of conservation of mass, which is established without considering relativity. In the system of relativity, it is modified to "conservation of mass and energy".

If we compress a spring, we must input energy from the outside, which will naturally lead to the improvement of relativistic mass. Ultimately, it is still a physical problem of the "mass energy equation". In chemical modification, there are subtle differences in the mass of each type of atom in different molecules, which is caused by different chemical bonds. Chemical bonds store chemical energy, and the essence of chemical energy in relativity is the loss of mass.Stainless Steel Spring Processing manufacturer.
