In this activity you will compare distance and displacement. Which term is more useful when making measurements? Choose a room that is large enough for all students to walk unobstructed. Make sure the total path traveled is short enough that students can walk back and forth across it multiple times during the course of a song. Have them measure the distance between the two points and come to a consensus.
When students measure their displacement, make sure that they measure forward from the direction they marked as the starting position. After they have completed the lab, have them discuss their results. If you are describing only your drive to school, then the distance traveled and the displacement are the same—5 kilometers. When you are describing the entire round trip, distance and displacement are different.
When you describe distance, you only include the magnitude , the size or amount, of the distance traveled. However, when you describe the displacement, you take into account both the magnitude of the change in position and the direction of movement. In our previous example, the car travels a total of 10 kilometers, but it drives five of those kilometers forward toward school and five of those kilometers back in the opposite direction. A quantity, such as distance, that has magnitude i. A quantity, such as displacement, that has both magnitude and direction is called a vector. This video introduces and differentiates between vectors and scalars.
It also introduces quantities that we will be working with during the study of kinematics. Define the concepts of vectors and scalars before watching the video. Hopefully you now understand the conceptual difference between distance and displacement. Understanding concepts is half the battle in physics. The other half is math. A stumbling block to new physics students is trying to wade through the math of physics while also trying to understand the associated concepts. This struggle may lead to misconceptions and answers that make no sense.
Once the concept is mastered, the math is far less confusing. You can calculate an object's displacement by subtracting its original position, d 0 , from its final position d f. In math terms that means. We also need to define an origin, or O. In Figure 2. If we left home and drove the opposite way from school, motion would have been in the negative direction. We would have assigned it a negative value. In the round-trip drive, d f and d 0 were both at zero kilometers. In the one way trip to school, d f was at 5 kilometers and d 0 was at zero km. You may place your origin wherever you would like. You have to make sure that you calculate all distances consistently from your zero and you define one direction as positive and the other as negative.
Therefore, it makes sense to choose the easiest axis, direction, and zero. In the example above, we took home to be zero because it allowed us to avoid having to interpret a solution with a negative sign. A cyclist rides 3 km west and then turns around and rides 2 km east. To solve this problem, we need to find the difference between the final position and the initial position while taking care to note the direction on the axis. The displacement is negative because we chose east to be positive and west to be negative.
We could also have described the displacement as 1 km west. When calculating displacement, the direction mattered, but when calculating distance, the direction did not matter. The problem would work the same way if the problem were in the north—south or y -direction. Physicists like to use standard units so it is easier to compare notes. SI units are based on the metric system.
The SI unit for displacement is the meter m , but sometimes you will see a problem with kilometers, miles, feet, or other units of length. If one unit in a problem is an SI unit and another is not, you will need to convert all of your quantities to the same system before you can carry out the calculation. Point out to students that the distance for each segment is the absolute value of the displacement along a straight path. On an axis in which moving from right to left is positive, what is the displacement and distance of a student who walks 32 m to the right and then 17 m to the left? Tiana jogs 1. She then turns back and jogs 0.
What are the displacement and distance she jogged? Physicists make calculations all the time, but they do not always get the right answers. It was supposed to orbit the planet and take readings from a safe distance. The American scientists made calculations in English units feet, inches, pounds, etc. This was a very costly mistake. Instead of orbiting the planet as planned, the Mars Climate Orbiter ended up flying into the Martian atmosphere. The probe disintegrated. The text feature describes a real-life miscalculation made by astronomers at NASA. The orbiter had to be close enough to the planet to take measurements and far enough away that it could remain structurally sound. One way to teach this concept would be to pick an orbital distance from Mars and have the students calculate the distance of the path and the height from the surface both in SI units and in English units.
Ask why failure to convert might be a problem. If students are struggling with a specific objective, the formative assessment will help direct students to the relevant content.

By the end of this section, you will be able to do the following: Describe motion in different reference frames Define distance and displacement, and distinguish between the two Solve problems involving distance and displacement. Teacher Support The learning objectives in this section will help your students master the following standards: 4 Science concepts. The student knows and applies the laws governing motion in a variety of situations. The student is expected to: B describe and analyze motion in one dimension using equations with the concepts of distance, displacement, speed, average velocity, instantaneous velocity, and acceleration; F identify and describe motion relative to different frames of reference.

The motion of the ball is independent of the reference frame and is same for different reference frames. The motion of the ball is independent of the reference frame and is different for different reference frames. The motion of the ball is dependent on the reference frame and is same for different reference frames. The motion of the ball is dependent on the reference frames and is different for different reference frames. Teacher Support Before students begin the lab, arrange a location where pairs of students can have ample room to walk forward at least several meters.

Teacher Support Help students learn the difference between distance and displacement by showing examples of motion. As students watch, walk straight across the room and have students estimate the length of your path. Then, at same starting point, walk along a winding path to the same ending point. Again, have students estimate the length of your path. Distance vs. Displacement In this activity you will compare distance and displacement.

Displacement is Mars Probe Explosion Figure 2. At one point the orbiter was just , feet above the surface, which was too close to stay in orbit. What was the height of the orbiter at this time in kilometers? Assume 1 meter equals 3. What does it mean when motion is described as relative? For example, imagine an employee who is angry with their boss. They take out their anger on their spouse when they get home.
Now angry themselves, the spouse might be irritable with their children. In turn, the kids might take their frustrations out on each other. Displaced interpersonal aggression can also lead to prejudice against specific social groups. For example, some scholars have argued that the animosity Germans felt toward the Jewish people following World War I may have been an example of displaced feelings of anger over the economic ramifications of the war. Rather than directing their collective anger toward their own actions or their own government, people redirected their rage toward a group of people they deemed to be less threatening targets.
This phenomenon is also known as scapegoating. Defense mechanisms are very common and are usually a normal aspect of daily functioning. Displacement as a defense helps us channel emotions and urges that could be considered inappropriate or harmful to more healthy, safe, or productive outlets. When used appropriately, defenses such as displacement protect us from negative feelings, help minimize disappointment , protect our self-esteem , and manage stress levels. But defense mechanisms like displacement can also be unhelpful if people rely on them too heavily, or when they lead to problematic behaviors and interactions with others.
Overuse of these mechanisms has been linked to psychological distress and poor functioning. Displacement serves as a way to redirect feelings, but it also has the potential to cause harm. There are several factors that influence how and when displacement occurs. Young children are more direct about expressing their feelings. Therefore, they are more likely to express their negative emotions toward the original target regardless of the appropriateness of the response. For example, a 4-year-old child is likely to simply yell at a parent when they are upset. On the other hand, a year-old might displace their frustration with a parent by fighting with a younger sibling. Highly upsetting urges or feelings might result in greater displays of emotion toward the substitute target.
For example, an inappropriate urge such as the desire to hit someone might be expressed as a highly charged emotional outburst such as yelling at a spouse. Most people have experienced taking out their negative emotions on a secondary target. While displacement can be a normal response, but it can cross the line into maladaptive or even abusive behavior. If a person relies on displacement as a defense mechanism to deal with all of their emotional upset, it is less likely to be unhelpful and may cause harm.
Overreliance on displacement or any other defense mechanism can be problematic, or at the very least, unhelpful. If you are concerned about your use of displacement as a defense mechanism, it's something you can address with a therapist or counselor as part of psychotherapy. Here are some ways you can look at your own behavior to get a better sense of whether you use displacement in a helpful way. One of the first steps is also one of the more difficult: observing your behavior and actions and determining whether displacement could be causing them. Displacement is not something that can be easily viewed. Often, it's only possible to make inferences based on what you can examine of your own behavior.
At this stage, it can be helpful to work with a therapist. They can look at your behavior from an "outside" point of view and help you see things from a more objective perspective. A therapist is able to witness and point out contradictions between your behavior and your words, body language , or other signals. For example, you might tell your therapist that you do not mind that your spouse works late nights and weekends, but your body language and your speech might suggest otherwise.
As you share more about your behavior, it might become clear that when you are short-tempered with your kids in the evening, it's really a sign of the frustration you feel with your spouse. Reflection is a strategy therapists can use to help you recognize when you are using defense mechanisms like displacement. With this strategy, your therapist reflects your feelings back to you in a way that encourages you to consider what you have done or said. The goal of using the reflection technique is to reveal concealed worries or concerns that played a role in your behavior.
For example, as you are telling your therapist about expressing anger at a coworker, you might reveal one of your underlying worries—that your new manager does not recognize your talents and efforts. Rather than expressing your emotions to your boss a threatening target , you took your frustration out on your coworker a less threatening target. Once you start to recognize episodes of unhealthy displacement in your own life, the next step is to look for purposeful ways to alter your thinking and behavior.
For example, if you are yelling at your spouse because you are displacing your frustrations from work, stop, step back, and take a moment to regain control. When you find yourself engaging in maladaptive behaviors caused by displacement, try to reframe the situation and find a healthier outlet for your feelings. Make a conscious effort to redirect your negative feelings toward an appropriate target. Alternative outlets could include writing about a situation and how you felt, participating in a sport or physical exercise, or engaging in a productive hobby. Like other psychological mechanisms of defense, displacement can be a normal and healthy way of coping with unconscious negative emotions.
However, overly relying on displacement as a way to handle negative feelings can be unhelpful and even destructive—particularly if you take your frustrations out on defenseless people around you. It can be hard to recognize our own displacement, if you are concerned about how you use this defense mechanism, therapy can help you see when your actions, words, or behaviors are really a defense mechanism. Once you learn to recognize displacement, you can take steps to challenge the defense mechanism and find more effective ways to cope. Ever wonder what your personality type means?
