Differences between position distance and displacement powerpoint
Stop the video right as you pass, and record the time. This is your initial time in seconds, and it's not zero! Find the time for every mile marker in the video they're green and counting down and make a table. Also find the average speed between the first mile marker and the very last one at the end of the video. As far as velocity is concerned, the direction is almost constantly westward.
The lab may download instead of playing. It did for me. Defining Motion Our study of physics opens with kinematics—the study of motion without considering its causes. Objects are in motion everywhere you look. Everything from a tennis game to a space-probe flyby of the planet Neptune involves motion. When you are resting, your heart moves blood through your veins.
Even in inanimate objects, atoms are always moving. How do you know something is moving? The location of an object at any particular time is its position. More precisely, you need to specify its position relative to a convenient reference frame. Earth is often used as a reference frame, and we often describe the position of an object as it relates to stationary objects in that reference frame. In other cases, we use reference frames that are not stationary but are in motion relative to Earth.
To describe the position of a person in an airplane, for example, we use the airplane, not Earth, as the reference frame. See Figure 2. Thus, you can only know how fast and in what direction an object's position is changing against a background of something else that is either not moving or moving with a known speed and direction.
The reference frame is the coordinate system from which the positions of objects are described. Figure 2. Why or why not? It is related to other English words, such as cinema movies, or moving pictures and kinesiology the study of human motion.
Your classroom can be used as a reference frame. In the classroom, the walls are not moving. Your motion as you walk to the door, can be measured against the stationary background of the classroom walls. You can also tell if other things in the classroom are moving, such as your classmates entering the classroom or a book falling off a desk.
You can also tell in what direction something is moving in the classroom. If you remained seated as your classmates left the room, you would measure their movement away from your stationary location. If you and your classmates left the room together, then your perspective of their motion would be change.
You, as the reference frame, would be moving in the same direction as your other moving classmates. As you will learn in the Snap Lab, your description of motion can be quite different when viewed from different reference frames. Relate this to the origin of a coordinate grid. Engage students in a discussion of how it is the difference in motion between the reference frame of the observer and the reference frame of the object that is important in describing motion.
The reference frames used in this chapter might be moving at a constant speed relative to each other, but they are not accelerating relative to each other.

The Concept of Displacement Displacement is defined as the distance travelled or moved in a specific direction. It takes into consideration the direction between the different points it seeks to measure; hence, displacement is a vector quantity. Thus, it has both magnitude and direction. Both distance and displacement have the same S. They could also be expressed in kilometre km , miles, etc.
Distinction between Distance and Displacement We need to understand the concepts of distance and displacement. Distance is the gap between two points with no regard to direction. On the other hand, displacement is distance covered in a particular direction. Therefore distance is a scalar quantity while displacement is a vector quantity. The only similarity between distance and displacement is that they have the same unit. Let us consider a girl who walked and covered a distance of 20m between two points A and B as shown in fig 1 and fig 2 below The two activities of the girl are not exactly the same.
In both figs. Now comes the confusion. One can always talk about a position as a displacement from an origin. In fact, in some systems this is a far easier approach because it treats points and vectors as one and the same. Likewise, I can always define a reference frame centered on the initial position of an object, and then its position in that frame is the same as its displacement. This is why the two terms are easy to confuse.
While they are different, we will often smoothly flow from one term to another. In the real world, ask questions. In the world of test taking, learn the language hints your textbooks use and pass your tests. Which brings us to distances. A distance is a length of a line in space. The distance between point A and point B is the length of a line between them.
However, we can also talk about the length of arbitrary curves, not just straight lines. This is what your homework problem is trying to do. I believe it was supposed to read "distance traveled," which is the length of the curve tracing the path the object takes.
