Fragmentation event resulting from in-orbit breakup of a satellite spawn multifarious debris particles which emanate from the source resulting in the distribution of velocities. However, the fragments generated from the event undergo certain perturbations in their velocities under the influence of the intensity and cause of the event. Therefore, magnitudes and directions of the velocity perturbations indicate the nature and intensity of the event. The work in the present manuscript describes two methods for calculating these velocity changes or perturbations. Further analysis on velocity perturbations were carried out for three different cases, namely, high intensity explosion, low intensity explosion and a collision in space.
