Vectors An object moves from point A to point B along the curved path shown. Supposing that we are not interested in the actual path followed but only in the result: That the object was ‘displaced’ from A to B. How do we represent this Displacement ? A B We represent it by an arrow: A B What information does the arrow give us? The length of the arrow is proportional to the distance between the endpoints and it points in the direction of the displacement. The displacement of an object is an example of a vector. The displacement of an object depends only on its starting point and its end point, it does not depend on the path taken. The two paths shown below correspond to the same displacement vector.
