The model displays the numerical solution to the equations of motion and shows how the forces change as the mass slides. Users can set the coefficients of friction and the spring constant. The model plots the position, velocity, and net force on the mass as a function of time as the system evolves and in order to show the asymmetry caused by the change in direction of the frictional force when sliding up and down the incline and the importance of friction in establishing equilibrium.
The Block and Spring on an Inclined Plane model was created using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_mech_newton_BlockAndSpringOnInclinedPlane.jar file will run the program if Java is installed.

changes by lookang include: relayout and customize to simple harmonic motion model on a horizontal plane. _view.drawingPanel.setAntialiasShapeOn(true); _view.drawingPanel.setAntialiasTextOn(true); if(v > 0) direction=-1; // bug removed by lookang else if (v < 0) direction =1; // bug removed by lookang
