Sample Learning Goals


For Teachers

This simulation shows a complete mechanical spring-mass system. The masses and the spring all experience frictional forces acting on them, which is graphed out on the right graph in the simulation.

The left graph contains the entire spring system, which moves according to the spring forces acting on it. The right panel shows the graph of the forward and backward frictions against time.

The parameters can be adjusted with the sliders at the top of the simulation.
