Particle separation from a four-particle-system

The paper deals with the effects of particle separation from a plane four-particle system. First, the process of particle separation, which is done with certain velocity, has been studied. Then, the motion of the remainder three-particle system with initial conditions which correspond to the velocity and angular velocity after particle separation has been investigated. Further, the attraction and resistance forces between particles have been considered and the influence of the damping force and the friction force have been analyzed as well. Thus, the final position of the particles and the geometrical configuration directly dependent on the certain velocity of the separated particle is obtained.
