[edit] Displacement
Distance is different from displacement. Displacement is the difference between your starting point and your finishing point.
[edit] Example of Displacement
A and B are 1 metre apart. Tom walks from A to B. Then Tom walks from B back to A. The distance Tom walked is 2 metres. Tom's displacement is 0 metres, because Tom started at A and finished at A.
