👉 In physics, a slab line is a mathematical object that represents a straight line in 2D space. In this context, it refers to a line segment that is not parallel to any other line but rather lies entirely within another line, forming an edge of a polygon or geometric shape. This concept arises from the idea of slicing a solid into thin slices perpendicular to the plane of the slice, which can then be considered as a line. The slabline concept allows for the calculation of the distance between
