This study conducted a comparative analysis of how the gravitational acceleration (g) is measured in secondary physics by using different experiments. Gravity is a basic concept in physics, and accurate measurements of g are necessary. We analyzed the concept of g used at secondary level of schools with regards to definitions, formula derivations and measurements methods. Comprehensive analysis with four types of experiments revealed that both simple pendulum and free-falling objects was useful not only for measuring the value of g easily but also for elucidating the significance of g theoretically and experimentally. Although, the formula and experimental methods to obtain the g value differ among these four methods, reasonable values of g were measured. Each method was found to have both advantages and disadvantages in terms of difficulty and interest for students to learn about the gravity with experiments. These results can help learners’ engagement in hands-on activities in the classroom and exacerbate their interest to measure the value of g practically which defines the falling objects attracted by the earths gravity force. Moreover, it can encourage and motivate teachers and curriculum developers to utilize various teaching methods for improvement of learners’ physics concepts.
