(b) “relative coordinates” x The notation above states that the coordinate “x” denotes the relative displacement between blocks 1 and 2. • If “x” is POSITIVE, then the distance between 1 and 2 has INCREASED (and the spring between the two blocks has been stretched). • If “x” is NEGATIVE, then the distance between 1 and 2 has DECREASED (and the spring between the two blocks has been compressed)....
