One of the key outcomes of collisional disruptions to the dust system is the velocity distribution of fragments. A series of laboratory impact experiments were carried out to obtain the mass-velocity and the position-velocity relation of the fragments by taking movie films, and films for tow impacts were completely analyzed.
