An improvised apparatus for studying the concept of center of gravity

Abstract

The lack of practical knowledge and application of many students regarding the scientific concepts they learned in their lecture classes owes much to the lack or scarcity of equipment in the laboratory. The development and use of improvised equipment is one solution to the problem. In this paper, the author puts forward an improvised apparatus for demonstrating and exploring the concept of center of gravity of rigid objects in the classroom or in the laboratory. Using nothing more than simple items that are readily available in a local bookstore, office supply store, or even in a sari-sari store, it is possible to construct an improvised apparatus that, with the appropriate experiment procedure, facilitates the determination of the center of gravity of objects via hanging.
