Development of Motion Learning Media and Energy Conservation Law Through Coaster Tracks Based on Logger Pro Analysis

Abstract

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: v train 0.027 m/s, a train 0.034 m/s 2 , average train velocity 0.02572 m/s and average train acceleration 0.03662 m/s 2 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 analysis.

Designing Technological Content Curriculum Materials Supported by Logger Pro: An Action Research

“…A relationship can be established between the graphics presented automatically as a result of the measurements and the graphics that are estimated by hand by the people who make the measurements (Milner-Bolotin & Moll, 2008). With the help of Logger Pro technology, which has started to take an important place in experimental measurements in science education, video recordings of the measured data can be created, and the comparative results of the data in desired time intervals can be evaluated by controlling the speed settings of the video recordings (Setiyani, Kristiyanto & Rondonuwu, 2019). Slopes, tangents and integral values in graphs can be found both by calculating and measuring, and the obtained data can be easily printed (Milner-Bolotin, Kotlicki & Rieger, 2007).…”

Development of Student Worksheet Discovery Model Based on Video Logger Pro Analysis to Improve Problem-Solving Skills of Physics Teacher Candidates

“…Solutions to increase student-solving skills are carried out with innovative learning methods and media one method is guided discovery. The guided discovery method is proven to improve problem-solving abilities (Hulukati et al, 2018), critical thinking skills, creative thinking skill, video-assisted guided discovery improves problem-solving abilities (Setiyani et al, 2019).…”
