Motion in one dimension is one of the important chapter in mechanics. It defines position, distance, and displacement and describes the differences between distance and displacement. Displacement is defined as the shortest distance x a onedimensional object is from a center point, or an origin. Any object is situated at point o and three observers from three different places are looking for same object, then all three observers will have different observations about the position of point o and no one will be wrong. The arrow points in the same direction as the vector. Before going to the original answer, lets understand a few facts.
