collisional
Relating to impacts
Collisional describes something relating to or resulting from collisions.
The term appears mainly in physics and astronomy, where it characterizes processes involving particles, molecules, or celestial bodies striking one another: collisional heating, collisional ionization, collisional dynamics of asteroid belts.
