7.4 Graphical Representation of Motion Graphs provide a convenient method to present basic information about a variety of events. For example, in the telecast of a one-day cricket match, vertical bar graphs show the run rate of a team in each over. As you have studied in mathematics, a straight line graph helps in solving a linear equation having two varlables To describe the motion of an object. we can use line graphs. In this case. line graphs show dependence of one physical quantity. such as distance or velocity, on another quantity, such as time. 7.4.1 DISTANCE-TIME GRAPHS The change in the position of an object with ume can be represented on the distance-time graph adopting a convenient scale of choice. In this graph, time is taken along the -axis and distance is taken along the -axis. Distance-time graphs can be employed under various conditions where objects move with uniform speed. non-uniform speed. remain at rest etc. Fig 7.3: Distance time graph of an object moving with uniform speed We know that when an object travels equal distances in equal intervals of time. it moves with uniform speed. This shows that the distance travelled by the object is directy proportional to ume taken. Thus, for unifon speed, a graph of distance travelled againa ime is a stralght line as shown in Fig, 73 The portion of the graph shows that the distance is increasing at a uniform rate. Note that. you can also use the term unifortm velocity in place of uniform speed if you take the magnitude of displacement equal to the distance travelled by the object along the -axds. We can use the distance-time graph to determine the speed of an object. To do so consider a small part of the distance-time graph shown in Fig 7.3. Draw a line parallel to the -axis from point and another line parallel to the -axis from point B. These two lines meet each other at point to form a triangle . Now, on the graph. AC denotes the time interval while BC corresponds to the distance . We can see from the graph that as the object moves from the point A to B. it covers a distance in time . The speed. of the object, therefore can be represented as We can also plot the distance-time graph for accelerated motion. Table 7.2 shows the distance travelled by a car in a time interval of two seconds. Table 7.2: Distance travelled by a car at regular time intervals 78
