Abstract

Physics is one of science branch that become the cornerstone of many of advanced technology development, so the process of learning physics should not only focused on the concept mastery but also concerning the discovery aspect. In that case, experiment activity has been really important in learning physics. One of the most common experiment activity which used to explain uniform rectinilier motion and accelerated uniform rectinlier motion is using Atwood Machine. From the observations, it is showed that the measure of the motion parameter has done manually using stopwatch and ruler. The result from this experiment was subjective and also it was cannot give exact characteristic of this two motion. One of the solution for this problem is use tracker application. In this experiment, a body is recorded using High Definition camera with 24 frame per second shutter speed. The result from data processing with tracker has shown that the graphic of position depend on time for uniform rectilinier motion (y=f(t)) is a linier line with positive gradient and the graphic of the velocity depend on time (v=f(t)) is flat line shaped. For the uniform accelerated rectilinier motion, the graphic of position depend on time (y=f(t)) is a graphic from quadratic function and the graphic of the velocity depend on time (v=f(t)) is a linier line with positive gradient. Based on the result of the data analysis, it is concluded that the use of tracker application on atwood machine is able to show the characteristic of uniform rectilinier motion and uniform accelerated rectilinier motion so it is worth to use in physics learning at school. Keywords: Uniform Accelerated Rectilinier Motion, Uniform Rectilinier Motion, Tracker, Atwood Machine.

Abstract

In the experiments, misconceptions can occur because of lack information or even incorrect information from the experiments performed. One of the experiments that are prone to misconceptions is a non uniform linear motion experiment. Generally, the misconceptions is the mass of objects affect for the acceleration of objects motion on the path of the sloping field. This research was conducted to compare the results of experimental data processing using two methods, that is using ticker timer and tracker application to determine more precise method, so it is expected to reduce the occurrence of misconception. This research was conducted by recording the dynamics of the mobility moves that change its mass using a high resolution camera with 24 frame / sec shooting speed. The data in the form of tape result of ticker timer in analysis using microcal origin software and video recording data were analyzed using tracker application. The result of data analysis shows that data processing using tracker produces more constant acceleration data compared with data from timer ticker band, so with application of tracker can be concluded there is no mass effect to acceleration motion of moving objects on sloping path. Utilization of tracker applications in the dynamics train experiment can be used as an alternative that can be used to reduce misconceptions on the teaching material of non uniform linear motion. Keywords: non uniform linear motion, tracker, misconception.
