[Physics Class Notes] on Distance Time Graph Pdf for Exam

Distance-time graphs show how far an object has travelled in a designated period of time. The graph shows distance versus time and is made up of a simple line graph.

1. On the Y-axis, the distance is plotted.

2. On the X-axis, time is plotted. 

Distance-time graphs show the speed of a vehicle changing along curved lines.

The Importance of Distance – Time Graphs

In studying the motion of bodies, we deal with distance-time graphs. A distance-time graph representing the motion of a body is obtained when we plot the data for distance and time for a body on a rectangular graph.

Distance vs. Time Definition

During the study of distance-time graphs, the three most critical components are time, speed, and distance. The vertical Y-axis of a graphical representation is the vertical time axis, while the horizontal X-axis is the horizontal distance axis. Then, once the axes are determined, it is easy to plot the values on the graph.

As the distance versus time graph shows, we can see the different variations of the body’s movement. For instance, when a graph plots as a straight line, this indicates that the body is moving at a fixed (or constant) speed.

To help students gain a better understanding of the topic, we have compiled some worked-out mathematical problems.

Consider the following graph that shows Ralph’s entire journey. Here are the results.

1. He covered a total distance.

2. He remained stationary for a period of time.

3. He travelled at an average speed of 17:15 to 17:45 (kilometers per hour).

1. By looking at the axis, it appears that Ralph first travelled 25 km, rested, and then returned home. Therefore, the total distance he travelled was 25km + 25km = 50 km. 

2. Ralph was in the station for one box’s duration, which is clear from the graph. Additionally, from the axis, it is clear that two boxes total equal 15 minutes. The time spent stationary would be 15/2 = 7.5 minutes.

3. First, you must estimate the gradient of the graph from 17:15 to 17:45 (30 minutes or 0.5 hours) to calculate the average speed between the points. As you can see, he increased his speed by five kilometers until he reached 25 kilometers. In total, he traveled 20 kilometers. Since the gradient is 20/0.5, his speed is 40 km/h.
