👉 In physics, a barrelwise path is an integral path that goes through all of the points on a curved surface. It represents the shortest distance between any two points on the surface. For example: 1) A line segment with endpoints at (0, 0), (2, 4), and (3, 6) forms a barrelwise path. The length of this path is √(2^2 + 4^2) ≈ 6.48 units.
