Aim: To use Tracker software to map the motion of a table tennis ball in the form of graphs
Apparatus: Retort stand, wooden block and metre rule
Materials: Table tennis ball and cellophane tape
Instructions:
1. Work in groups.
2. Scan the QR code to download Tracker software.
3. Set up the apparatus as shown in Figure 2.22 using two
metre rules arranged in the shape of a “V” to form an Download Tracker software

4. Record a video of the motion of the table tennis ball along a straight line.
5. Use Tracker software to analyse the motion of the table tennis ball in the video using
displacement-time, velocity-time and acceleration-time graphs.
6. Figure 2.23 shows examples of graphs that you can obtain using the software.
Graph of horizontal displacement Graph of vertical displacement Graph of speed against time

7. Discuss and interpret the motion of the table tennis ball based on the graphs obtained.
8. Analyse the motion of the table tennis ball from the graphs.
9. Present your interpretation and analysis of the graphs.
