Ejecta dynamics is a field of research that focuses on the study of the behavior and characteristics of materials ejected from a source, such as an explosion, impact, or volcanic eruption. This research area examines the trajectory, velocity, distribution, and impact of the ejecta, as well as the mechanisms that govern its movement and dispersion. Ejecta dynamics can have implications for a wide range of applications, including understanding the formation of craters, predicting the spread of debris from natural disasters, and developing methods for mitigating the effects of explosive events.
