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: 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 analysis.Telah dilakukan penelitian untuk mengetahui grafik keterkaitan posisi dan kecepatan terhadap waktu, untuk benda yang meluncur di atas landasan magnetik dengan menerapkan metode Research and Development. Pengambilan data dilakukan dengan menggunakan video rekaman gerak kereta yang dianalisis menggunakan Logger Pro. Hasil analisis direpresentasikan dalam bentuk data dan grafik. Berdasarkan analisis dan fitting data menggunakan Logger Pro diperoleh nilai sebagai berikut   vkereta 0,027 m/s, akereta 0,034 m/s2, v rata-rata kereta 0,02572 m/s dan arata-rata kereta 0,03662 m/s2 dengan nilai RMSE (Root Mean Square Eror) sebesar 0,013 m. Nilai percepatan yang diperoleh sangat kecil dan hampir mendekati nol, sehingga dapat dikatakan bahwa benda mengalami gerak lurus beraturan. Representasi grafik kecepatan terhadap waktu memperlihatkan pertambahan kecepatan yang tidak konstan. Hal ini dikarenakan masih terdapat gesekan yang terjadi antara kereta dengan landasan maupun gesekan antar magnet di sepanjang lintasan dengan gaya gesek 4,566 N. Nilai energi kinetik, energi potensial, dan energi mekanik dapat ditentukan besarnya menggunakan data hasil analisis Logger Pro.

基于Logger Pro分析的过山车轨迹运动学习媒体开发与节能规律
应用研究与开发方法,研究了在磁基础上滑动物体的位置、速度与时间的关系。数据检索是通过使用Logger Pro分析的视频列车运动记录来完成的。分析结果以数据和图形的形式表示。利用Logger Pro对数据进行分析和拟合,得到车次为0.027 m/s,列车为0.034 m/s2,列车平均速度为0.02572 m/s,列车平均加速度为0.03662 m/s2,均方根误差为0.013 m。得到的加速度值很小,几乎接近于零,因此可以说,经历不规则直线运动的物体。速度随时间的曲线图显示速度的增加不是恒定的。这是因为列车与跑道之间仍然存在摩擦,沿着轨道的磁体之间也存在摩擦,摩擦力为4566 n。利用Logger Pro的分析结果可以确定动能、势能和机械能的值。Telah dilakukan penelitian为她mengetahui grafik keterkaitan posisi丹kecepatan terhadap waktu,为她benda杨meluncur di ata landasan magnetik dengan menerapkan metode研发。彭甘比兰数据,dilakukan, dengan, menggunakan,视频,rekaman, gerak, kereta, yang dianalis, menggunakan记录器Pro。Hasil分析具有代表性的亚洲dalam bentuk数据。Berdasarkan分析和拟合数据menggunakan Logger Pro diperoleh nilai sebagai berikut vkereta 0,027 m/s, akereta 0,034 m/s2, v rata-rata kereta 0,02572 m/s和arata-rata kereta 0,03662 m/s2, dengan nilai RMSE(均方根误差)sebesar 0,013 m。Nilai percepatan yang diperoleh sangat kecil dan hampir mendekati nol, sehinga dapat dikatakan bahwa benda mengalami gerakus beraturan。代表尼泊尔的尼泊尔人,尼泊尔人,尼泊尔人,尼泊尔人。1 .能量动力学、能量势、能量动力学、能量势、能量势、能量势、能量势、能量势、能量势、能量势、能量势、能量势、能量势
