👉 "Stech" is a mathematical concept in physics and mathematics that represents an object's motion. It can be defined as "the angular displacement from one point on a straight line to another." In other words, it represents the change in angle between two points on a curve or surface.
For example, if you have a curved path such as a track, a ball rolling down this track, or an object sliding along a frictionless surface, then the stech of the object would represent its motion
