After completing Lab 4 Acceleration Due To Gravity I can conclude that using a direct method (free falling activity) in obtaining acceleration is more precise than compared to the indirect method (pendulum swing activity). Thusly when I compared my results of each experiment, the free falling measurements were not so great, but closer to the earth’s acceleration. For example, my last measurement of the free falling activity was approximately 985.11 cm/s^2, which was very close to the earth’s acceleration. On the other hand my last measurement on the pendulum swing activity my last measurement was 2196.14 cm/s^2, which was very off from the earth’s acceleration. It is possible to assume errors in my calculations may had alter any of my measurements. Also possible errors in the experiment could have also altered my results. I can honestly say it is not that simple to obtain multiple measure close to the earth’s average. This experiment was overall simple to conduct, but obtaining really good results compared to the earth’s average is the challenge.
I really enjoyed conducting this experiment using two different methods to obtain acceleration. My favorite activity was the free falling activity, because I actually obtain one very good measure. These experiments were pretty simple once I got the hang of using the equipment. I thought this experiment was quite interesting looking at my results and comparing them to the average. I had no dislikes on these experiments. Overall this experiment was informative and it has open my about the earth’s acceleration
