👉 Flecking is a term used in various fields of science, particularly in physics and astronomy. It refers to the process by which gas molecules align themselves into an orderly pattern or structure, often with respect to their respective velocities (speeds) within a fluid or medium. In physics, flecking can be explained using the concept of momentum conservation. When two particles collide, they exchange kinetic energy in the form of heat and light. The momentum of one particle is conserved because it travels at
