About

an open source physics at Singapore simulation based on codes written by Wolfgang Christian and Loo Kang WEE.

Introduction

The Horizontal Mass and Spring Harmonic Oscillator mobile JavaScript model illustrates the forces and dynamics of a simple oscillator. This simulation uses the accelerometer on your mobile device to read the direction of the gravitation field g. You may need to lock the orientation of your screen to maintain a fixed view as you tilt your device. For use on computers without an accelerometer or for classroom use, the "No sensor" mode simulates a tilted device in the view. See also the Vertical Mass and Spring mobile JavaScript model.

A force body (free body) diagram showing the spring force (blue), the normal force (red), the gravitational force (black), and the force of friction (green) is shown. Users can set the initial position and velocity and you can adjust the viscous damping (friction) coefficient when the simulation is paused. Test your knowledge of oscillator dynamics by answering the following questions and comparing your answers with the simulation results.

Initial values, such as x0 and v0, can be set when the simulation is paused but not when the simulation is running. (Non-editable input fields have a grey background.) You may also drag the mass when the simulation is paused. The reset button returns the system to its default state while the reset time button returns the system to the previous values of x0 and v0.

Interesting Fact

This app produce real numbers to coincident with the real world data.

This App is paid if you want to further support the development of Open Source Physics (Thank you for your support and contribution!)

and if don't want to pay, the free version is available here.
