Unformatted text preview: 1 + W 2 = 0 . Now compare the two different paths taken from A to B in part b). The work on the first path is the same as part a), simply W 1 . The direction of travel on the second path is reversed in b), implying that the work done over the path is negated, or equal to  W 2 . But we know from a) that  W 2 = W 1 . Thus the work done over path 1 and path 2 in part b) is the same! This concept, called path independence, is incredibly useful, as we will soon see. Stated verbally: The work done by a conservative force in moving a body from an initial location to a final location is independent of the path taken between the two points...
