Adding And Subtracting Vectors Graphically William Hopper S Addition Now that we have the skills to work with vectors in two dimensions, we can apply vector addition to graphically determine the resultant vector, which represents the total force. consider an example of force involving two ice skaters pushing a third as seen in figure 5.7 . Vector addition: head to tail method. the head to tail method is a graphical way to add vectors, described in figure below and in the steps following. the tail of the vector is the starting point of the vector, and the head (or tip) of a vector is the final, pointed end of the arrow. figure.
Adding And Subtracting Vectors Graphically William Hopper S Addition The head to tail graphical method of vector addition works for any number of vectors. it is also important to note that the resultant is independent of the order in which the vectors are added. therefore, we could add the vectors in any order as illustrated in figure 3.18 and we will still get the same solution. Summary. the graphical method of adding vectors a a and b b involves drawing vectors on a graph and adding them using the head to tail method. the resultant vector r r is defined such that a b = r a b = r. the magnitude and direction of r r are then determined with a ruler and protractor, respectively. Figure 4. head to tail method: the head to tail method of graphically adding vectors is illustrated for the two displacements of the person walking in a city considered in figure 2. (a) draw a vector representing the displacement to the east. (b) draw a vector representing the displacement to the north. For the analytical method of vector addition and subtraction, we use some simple geometry and trigonometry, instead of using a ruler and protractor as we did for graphical methods. however, the graphical method will still come in handy to visualize the problem by drawing vectors using the head to tail method.

Example 1: adding vectors graphically using the head to tail method: a women takes a walk. use the graphical technique for adding vectors to find the total displacement of a person who walks the following three paths (displacements) on a flat field. first, she walks 25.0 m in a direction north of east. then, she walks 23.0 m heading north of. The graphical method of subtracting vector b b from a a involves adding the opposite of vector b, b, which is defined as −b. − b. in this case, a −b = a (−b) = r. a − b = a (− b) = r. then, the head to tail method of addition is followed in the usual way to obtain the resultant vector r. r.
