Group Activity 1: The race is on Names: Manzur, Munifa W. Grade/Strand/Section: 12-STEM Arellano Ibrahim, Aishraneem S. Belotendos, Sherly Ann M. I. Objectives ๏ Calculate the average speed of a moving body II. Materials ๏ meter stick ๏ stop watch III. Procedure
1. Select three (3) of your members to run the #0-m distance. 2. Choose an area where the members will run. Use a meter stick to measure the desired distance. 3. Make 10-m intervals along the runway. Record the time the runner passes the 10m, 20m, and 30m mark. 4. Determine the average speed by dividing the distance by time taken. 5. DO the same to the other 2 runners. IV.

1. Compare the first runnerโs speed to that runner 2 and 3 ๏ By comparing the three runners in this activity, the speed of the first runner in the 10m mark is slower than the second runner but faster than the third runner. In the 20m mark, the first runner is still slower than the second runner but this time the first runner is slower than the third runner. On the last mark or the 30m mark, the first runner obtained the slowest speed than the second and third runner. 2. Did each runner achieve a constant speed during his/her travel? ๏ Looking at the three tables above, the three runners didnโt achieve a constant speed as they travel the 10m, 20m, and 30m mark. 3. Show your computation for each runnerโs average speed.

C.3 Third runnerโs average speed running the 30m mark
4. Plot a distance versus time graph of your data. VI. Conclusion
Therefore we conclude that, as the runner travel in a short period of time then the average speed of the runner is faster or higher than the other runners. Just for instance, the first runner obtained a 3.42 seconds running a 10m mark while the second runner obtained 3.20 seconds and the third runner obtained 3.59 seconds, it concludes that the first runner ran the 10m mark slower than the second runner but faster than the third runner. Additionally, we also observe that the runner didnโt maintain a constant speed as they travelled the different distances. For the first runner, as she travelled the 10m, 20m, and 30m mark her speed is changing form fast to slow and fast again while the speed of the second runner is increasing as the distance is also increases and lastly, the third runner obtained a increasing speed as she ran the different distances just like the second runner.
