Abstract
Analysis accurately for observing the non-conservative forces on the object‘s motion can contribute to a deeper understanding of Conservative Laws. A study to design the laboratory-based media was implemented using research and development methods to produce an experimental device that can observe the changes in mechanical energy (same as non-conservative energy). The method chosen is 4D which consists of defining, designing, developing, and disseminating. In this study, the discussion is limited to the stage of developing for self-evaluation data. The results for defining are the analysing data of students needs, for the designing are the calculation of the rail track’s size and shape, and for the development are the mini roller coaster device. Utilize the video-based laboratory, the media can be used for analysing the change of vertical acceleration and height with time and the changes of mechanical energy that can show the existence of the non-conservative energy.
