Mobile Learning of Physical Pendulum in Android-Based Smartphones

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
