👉 In mathematics, "neckar" is a mathematical concept used to understand and describe the behavior of the fundamental unit of a system. It refers to a small change in one coordinate that can cause a large change in another coordinate within the same system.
For example, consider a system consisting of two particles moving along a straight line. If one particle moves forward with velocity v1, while the other moves backward with velocity -v1, and both particles move through the same distance d, then it is
