Graphing Motion Name ____________________________________

Part A

The graph in Figure 1 shows data for two objects that start from rest and travel in a straight

line. Interpret the graph to answer the following questions.

Figure 1 Movement of Objects A and B

 

1. What does each point plotted on the graph in Figure 1 represent?

_____________________________________________________________________________________________

2. What does line A tell you about the speed at which object A moved?

_____________________________________________________________________________________________

3. What does line B tell you about the speed at which object B moved?

_____________________________________________________________________________________________

4. The lines that connect plotted points on a graph are called the curve of the graph. What can you tell about the way object B moved from looking at the curve?

_____________________________________________________________________________________________

5. Which object moved faster for 50 meters? How do you know?

_____________________________________________________________________________________________

6. What was object As speed? Show your calculations.

_____________________________________________________________________________________________

7. What was object Bs speed from start to point b? From point b to point c? From point c to

point e? Show your calculations.

_____________________________________________________________________________________________

8. What was the average speed of object B from start to point e?

_____________________________________________________________________________________________


Part B

Data Table 1 shows the speed of object C at different times as it moves. Use the information in Data Table 1 to plot a curve on the graph in Figure 2. Fill in the third column on the data table by calculating the speed of the object.
