Tethered Mass and Spring Model 

written by Wolfgang Christian

The Tethered Mass and Spring model shows a mass constrained to move in the x-direction by a horizontal rod and connected to a spring of natural length L = 10. One end of the spring is connected to a movable (draggable) ceiling and the other end is connected to the mass. Users can drag the mass along the rod and users can control the height of the ceiling H by dragging which changes the stretch of the spring. The height H, the spring constant k, and the natural length of the spring L can also be adjusted using the sliders at the bottom of the position vs. time graph.

The Tethered Mass and Spring model was created using the Easy Java Simulations (EJS) modeling tool.  It is distributed as a ready-to-run (compiled) Java archive.  Double click the ejs_mech_lagrangian_TetheredMassAndSpring.jar file to run the program if Java is installed.
