The learning objectives in this section will help your students master the following standards:. Recall that a vector is a quantity that has magnitude and direction. For example, displacement, velocity, acceleration, and force are all vectors. In one-dimensional or straight-line motion, the direction of a vector can be given simply by a plus or minus sign. In two dimensions, a vector describes motion in two perpendicular directions, such as vertical and horizontal.

For vertical and horizontal motion, each vector is made up of vertical and horizontal components. In a one-dimensional problem, one of the components simply has a value of zero.

For two-dimensional vectors, we work with vectors by using a frame of reference such as a coordinate system. Recall how velocity, displacement and acceleration vectors are represented.

Figure 5. The person first walks nine blocks east and then five blocks north. Her total displacement does not match her path to her final destination. The displacement simply connects her starting point with her ending point using a straight line, which is the shortest distance.

We use the notation that a boldface symbol, such as D , stands for a vector. Note that her displacement would be the same if she had begun by first walking five blocks north and then walking nine blocks east.

In this text, we represent a vector with a boldface variable. For example, we represent a force with the vector F , which has both magnitude and direction.

The head-to-tail method is a graphical way to add vectors. The tail of the vector is the starting point of the vector, and the head or tip of a vector is the pointed end of the arrow.

The following steps describe how to use the head-to-tail method for graphical vector addition. Ask students what they feel the direction of resultant motion will be. How would they represent this graphically? Demonstrate the head-to-tail method of adding vectors, using the example given in the chapter. Ask students to practice this method of addition using a scale and a protractor. How about the order of addition?

Would that make a difference? Introduce negative of a vector and vector subtraction. This video shows four graphical representations of vector addition and matches them to the correct vector addition formula. Vector subtraction is done in the same way as vector addition with one small change. We add the first vector to the negative of the vector that needs to be subtracted. A negative vector has the same magnitude as the original vector, but points in the opposite direction as shown in Figure 5.

This is true for scalars as well as vectors. Global angles are calculated in the counterclockwise direction. The clockwise direction is considered negative. 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. In problems where variables such as force are already known, the forces can be represented by making the length of the vectors proportional to the magnitudes of the forces.

For this, you need to create a scale. For example, each centimeter of vector length could represent 50 N worth of force.

Once you have the initial vectors drawn to scale, you can then use the head-to-tail method to draw the resultant vector. The length of the resultant can then be measured and converted back to the original units using the scale you created.

You can tell by looking at the vectors in the free-body diagram in Figure 5. Note, however, that the forces are not equal because they act in different directions. If, for example, each force had a magnitude of N, then we would find the magnitude of the total external force acting on the third skater by finding the magnitude of the resultant vector.

Since the forces act at a right angle to one another, we can use the Pythagorean theorem. For a triangle with sides a, b, and c, the Pythagorean theorem tells us that. Applying this theorem to the triangle made by F 1 , F 2 , and F tot in Figure 5. Another scenario where adding two-dimensional vectors is necessary is for velocity, where the direction may not be purely east-west or north-south, but some combination of these two directions.

In the next section, we cover how to solve this type of problem analytically. 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. Graphically represent each displacement vector with an arrow, labeling the first A , the second B , and the third C. Make the lengths proportional to the distance of the given displacement and orient the arrows as specified relative to an east-west line.

Use a protractor to measure the direction of R. While the direction of the vector can be specified in many ways, the easiest way is to measure the angle between the vector and the nearest horizontal or vertical axis.

Since R is south of the eastward pointing axis the x -axis , we flip the protractor upside down and measure the angle between the eastward axis and the vector, as illustrated in Figure 5. Using its magnitude and direction, this vector can be expressed as. The head-to-tail graphical method of vector addition works for any number of vectors. It is also important to note that it does not matter in what order the vectors are added.

Changing the order does not change the resultant. For example, we could add the vectors as shown in Figure 5. Recall how these forces can be represented in a free-body diagram. Giving values to these vectors, show how these can be added graphically. A woman sailing a boat at night is following directions to a dock.

The instructions read to first sail If the woman makes a mistake and travels in the opposite direction for the second leg of the trip, where will she end up? We can represent the first leg of the trip with a vector A , and the second leg of the trip that she was supposed to take with a vector B. These steps are demonstrated in Figure 5. Because subtraction of a vector is the same as addition of the same vector with the opposite direction, the graphical method for subtracting vectors works the same as for adding vectors.

A boat attempts to travel straight across a river at a speed of 3. The river current flows at a speed v river of 6.

What is the total velocity and direction of the boat? You can represent each meter per second of velocity as one centimeter of vector length in your drawing. We start by choosing a coordinate system with its x-axis parallel to the velocity of the river. Because the boat is directed straight toward the other shore, its velocity is perpendicular to the velocity of the river. We draw the two vectors, v boat and v river , as shown in Figure 5. Using the head-to-tail method, we draw the resulting total velocity vector from the tail of v boat to the head of v river.

By using a ruler, we find that the length of the resultant vector is 7. Plot the way from the classroom to the cafeteria or any two places in the school on the same level.

Ask students to come up with approximate distances. Ask them to do a vector analysis of the path. What is the total distance travelled? What is the displacement? In this simulation , you will experiment with adding vectors graphically.

Click and drag the red vectors from the Grab One basket onto the graph in the middle of the screen. These red vectors can be rotated, stretched, or repositioned by clicking and dragging with your mouse. Check the Show Sum box to display the resultant vector in green , which is the sum of all of the red vectors placed on the graph.

To remove a red vector, drag it to the trash or click the Clear All button if you wish to start over. You can check the resultant by lining up the vectors so that the head of the first vector touches the tail of the second.

Continue until all of the vectors are aligned together head-to-tail. You will see that the resultant magnitude and angle is the same as the arrow drawn from the tail of the first vector to the head of the last vector. Rearrange the vectors in any order head-to-tail and compare. The resultant will always be the same. True or False—The more long, red vectors you put on the graph, rotated in any direction, the greater the magnitude of the resultant green vector.

True or False—A person walks 2 blocks east and 5 blocks north. Another person walks 5 blocks north and then two blocks east. The displacement of the first person will be more than the displacement of the second person.
