If the impact was more of a grazing collision, the fragments will create a spray in roughly the direction of the smaller object's original motion.Įach fragment is given a radius that varies randomly from what would be expected from the fragment's mass and the density of the larger body. For example, if the impact was head-on, the fragments will mostly be reflected backwards in the direction the smaller object came from. The direction of the velocity vector of each fragment is randomly chosen from within a cone whose angle depends on the impact angle of the collision. This transferred mass, M trans, is equal the the mass contained in the volume of the region where the two objects overlap, V overlap: When two objects collide, mass is transferred from the smaller to the larger object. Collision fragmentation (as opposed to Roche fragmentation or friction fragmentation can be individually controlled in the Sim Settings Menu. The production of all fragments can be turned off using the Fragment toggle in the Sim menu or the Create Fragments toggle in the full Sim Settings Menu.Collisions can be turned off using the Collide toggle in the Sim menu in the bottom bar, or using the Detect Collisions toggle in the full Sim Settings Menu.The mass and velocity of each colliding object will influence the outcome of the collision, and determine whether fragmentation occurs.
