Mass and Spring Simple Harmonic Oscillator JS Model
written by
Wolfgang Christian, Francisco Esquembre, and Colleen L. Countryman
The Mass and Spring Simple Harmonic Oscillator mobile JavaScript model illustrates the forces and dynamics of a simple oscillator. This simulation uses the accelerometer on mobile devices to read the direction of the gravitation field g. You may, of course, need to lock the orientation of your screen to maintain a fixed view as you rotate your device. For use on computers without an accelerometer or for classroom use, the demo mode simulates a gravitational field in the y-direction.
The Mass and Spring Simple Harmonic Oscillator mobile JavaScript Model was developed using version 5 of the Easy Java Simulations (EJS 5) modeling tool. Although EJS is a Java program, EJS 5 creates stand alone JavaScript programs that run in almost any browser.
Please note that this resource requires
at least version 1.5 of Java (JRE).

9-12: 4F/H1. The change in motion (direction or speed) of an object is proportional to the applied force and inversely proportional to the mass.
4G. Forces of Nature
6-8: 4G/M1. Every object exerts gravitational force on every other object. The force depends on how much mass the objects have and on how far apart they are. The force is hard to detect unless at least one of the objects has a lot of mass.
11. Common Themes
11B. Models
6-8: 11B/M2. Mathematical models can be displayed on a computer and then modified to see what happens.
AAAS Benchmark Alignments (1993 Version)
4. THE PHYSICAL SETTING
E. Energy Transformations
4E (9-12) #1. Whenever the amount of energy in one place or form diminishes, the amount in other places or forms increases by the same amount.
F. Motion
4F (6-8) #3. An unbalanced force acting on an object changes its speed or direction of motion, or both. If the force acts toward a single center, the object's path may curve into an orbit around the center.
