Collision dynamics is a research area within the field of physics that focuses on studying the behavior and outcomes of collisions between particles, atoms, molecules, or other objects. This research involves investigating the forces and energies involved in collisions, as well as the resulting changes in momentum, velocity, and direction of the colliding objects. Collision dynamics research is important for understanding fundamental physical principles and processes, such as energy exchange, momentum conservation, and the behavior of matter at a microscopic level. This field has wide-ranging applications in various scientific disciplines, including astrophysics, chemistry, material science, and nuclear physics.
