Experiments of the law of conservation of mechanical energy using video tracker in high school learning

Props have been made to prove the law of conservation of mechanical energy using a video tracker, a miniature road Roller Coaster is a teaching aid that will be used for experiments. Through this learning media, it is hoped that it can help the physics learning process of Covid-19. The learning implementation is carried out in one of the high schools in West Bandung Regency in the even semester of the 2019/2020 school year. Determination of the research area using the method of the purposive sampling area, which means the area was chosen deliberately based on specific objectives and considerations. The population in this study were all students of class X MIPA. Using a video tracker is very helpful in the experiential process, the results of the implementation of this learning media can be implemented well as indicated by the results of the achievement of student indicators.
