👉 In physics, a poli- is an angle that results from the rotation of two or more objects in a straight line. This phenomenon can be observed in various contexts including automobiles, airplanes, and spacecrafts. When two or more objects are rotated at the same rate, they will tend to align in one plane (or poli-plane) if their orientations are perpendicular to each other. The angle between these two planes is called the polar angle of the object.
