- W2083343267 abstract "Many high school students have difficulties in learning physics. These difficulties occur due to inappropriateness models, methods, and instructional media used by teachers. One way to solve this problem is to create a mobile learning. This study produces a mobile learning of physical pendulum on Android- based smartphones. Theory and experiment of physical pendulum have been conducted previously for validation. The physical pendulum system consists of a metal rod and two identical cylinders attached together at the rod where the attachment position can be changed along the rod. Simulation parameters are initial angle (0 o ≤θ0≤90 o ), rod mass (mb), rod length (0<L≤1.5m), total mass of cylinders (ms), radius of cylinders (0<R≤0.2m), and distance from upper end of the rod to center mass of the cylinders (0<OA<L). The simulation parameters are used to determine the oscillation period (T) of physical pendulum and the acceleration due to gravity of the earth. The period T remains constant with the variation of θ0, mb, ms, and R. However, T changes linearly against L. The position of the cylinders determines the center of mass of physical pendulum and T changes linearly against the distance from rotation axis to the center of mass of the system. The acceleration due to gravity of the earth remains constant with the changes of the simulation parameters. This simulation is done using eclipse program and can be run at least at Android 2.2-based smartphones. Simulation for a number (n) oscillation can also be shown. In addition to the simulation, physical pendulum material is also provided in this mobile learning." @default.
