This book uses the If we call the horizontal axis the x x size 12, velocity increases until 55 s and then becomes constant, since acceleration decreases to zero at 55 s and remains zero afterward. When two physical quantities are plotted against one another in such a graph, the horizontal axis is usually considered to be an independent variable and the vertical axis a dependent variable. ![]() Slopes and General Relationshipsįirst note that graphs in this text have perpendicular axes, one horizontal and the other vertical. This section uses graphs of position, velocity, and acceleration versus time to illustrate one-dimensional kinematics. Graphs not only contain numerical information they also reveal relationships between physical quantities. time.Ī graph, like a picture, is worth a thousand words. Determine average or instantaneous acceleration from a graph of velocity vs.Determine average velocity or instantaneous velocity from a graph of position vs.Describe a straight-line graph in terms of its slope and y-intercept.By the end of this section, you will be able to: We recommend using aĪuthors: Paul Peter Urone, Roger Hinrichs In Two-Dimensional Kinematics, we apply concepts developed here to study motion along curved paths (two- and three-dimensional motion) for example, that of a car rounding a curve. In this chapter, we examine the simplest type of motion-namely, motion along a straight line, or one-dimensional motion. Such considerations come in other chapters. In one-dimensional kinematics and Two-Dimensional Kinematics we will study only the motion of a football, for example, without worrying about what forces cause or change its motion. The word “kinematics” comes from a Greek term meaning motion and is related to other English words such as “cinema” (movies) and “kinesiology” (the study of human motion). Our formal study of physics begins with kinematics which is defined as the study of motion without considering its causes. An understanding of acceleration, for example, is crucial to the study of force. The motion detector should be level with, and about 1 m away from, the pendulum bob when it hangs at rest. Place the motion detector near a pendulum with a length of 1 to 2 m as shown in Figure 1. Questions about motion are interesting in and of themselves: How long will it take for a space probe to get to Mars? Where will a football land if it is thrown at a certain angle? But an understanding of motion is also key to understanding other concepts in physics. Connect the motion detector to your Chromebook, computer, or mobile device. And even in inanimate objects, there is continuous motion in the vibrations of atoms and molecules.

When you are resting, your heart moves blood through your veins. Graphical Analysis of Motion - The graph below shows the position vs time for an object in motion. Everything from a tennis game to a space-probe flyby of the planet Neptune involves motion. Objects are in motion everywhere we look. ![]()
