In the inertia experiment, the spring stiffness coefficient of the cantilever has been regarded as a constant. When changing the mass of the calibration block, whether the spring stiffness coefficient k of the cantilever will affect the experimental results is not clear. In this paper, the spring stiffness coefficient and the inverse relationship between the spring stiffness coefficient and the mass of the cantilever are used to show that the spring stiffness coefficient k of the cantilever is not affected by the mass, so it can be treated as a constant.
