  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.
