Understanding the intriguing physical effects of long-range interactions is a common theme in a host of physical systems. In this work, based on the classical screened Coulomb interacting ring model, we investigate the dynamical effects of the long-range interaction from the unique perspective of analyzing the dynamical response of the system to disturbance. We reveal the featured dynamics brought by the long-range interaction, including the efficient transformation of the disturbance into the uniform global rotation of the system, the suppression of the intrinsic noise, and the fast relaxation of particle speed.
