摘要:Research has been conducted to find out relation position and speed to time, for objects that glide on a magnetic foundation by applying the Research and Development method. Data retrieval is done by using video train motion recordings which are analyzed using Logger Pro. The results of the analysis are represented in the form of data and graphics. Based on the data analysis and fitting using the Logger Pro, the following values are obtained: vtrain 0.027 m/s, atrain 0.034 m/s2 , average train velocity 0.02572 m/s and average train acceleration 0.03662 m/s2 with RMSE (Root Mean Square Error) value of 0.013 m. The acceleration value obtained is very small and almost close to zero, so it can be said that objects that experience irregular straight motion. The graph representation of velocity over time shows an increase in speed that is not constant. This is because there is still friction between the train and the runway and friction between magnets along the track with friction forces 4,566 N. The value of kinetic energy, potential energy, and mechanical energy can be determined by using the results of Logger Pro analysi.
