Note: When running this simulation on a tablet or smart-phone, set the parameters, then press the Play button. When running this simulation on a computer, be sure to uncheck “Accelerometer,” then set the parameters and press the Play button.

Block On An Incline: Coefficient of Friction

Select trial A, B, C, or D and find the static coefficient of friction for the Block Sliding On An Incline. 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, disable the "Accelerometer" and use the slider to tilted the table in the view.

Note: You can observe the force vectors when the simulation is paused but you must press the Play button to observe the motion.

The Block Sliding On An Incline Plane mobile JavaScript Model was developed by Wolfgang Christian 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.
