Free Collisions in a Microgravity Many-Particle Experiment. IV. - Three-Dimensional Analysis of Collision Properties
Icarus(2015)
Abstract
•We conducted a microgravity experiment to investigate free collisions of dust aggregates.•We found 4 out of 52 collisions to lead to sticking, the others to rebound.•Collision velocities may be investigated in 2D with little error.•The coefficient of restitution and collision parameter of a collision have to be analyzed in 3D.
