This information can be used to understand the early stages of planetary formation and the evolution of particles in rings systems. The collisions take place in a 1-m evacuated chamber, and both particles are in free-fall. This enables us to study collisions at low velocities (&lt; 1 m\/s) like those in planetary ring systems and some collisions in protoplanetary disks. We observe the collision with a high-frame-rate camera and track the positions of each particle. We perform similar experiments in our drop tower with the <a href=\"https:\/\/sciences.ucf.edu\/physics\/microgravity\/experiments\/coda\/\" target=\"_blank\" rel=\"noopener\">CODA<\/a>\u00a0experiment.
