Four-Spring Accelerometer JS Model
written by Wolfgang Christian
The Four-Spring Accelerometer mobile JavaScript Model shows how a mobile device detects acceleration.  The simulation displays the forces and dynamics of a small mass connected to four walls by springs and it is designed to use  the accelerometer on your mobile device to respond to the direction of the gravitation field g and the mobile device's xy-acceleration. 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, uncheck Sensor to simulate a tilted device in the view.

The Four-Spring Accelerometer 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.

### AAAS Benchmark Alignments (2008 Version)

#### 4. The Physical Setting

4F. Motion
• 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.
