Spring Motion Model 

written by Andrew Duffy

The Spring Motion Model shows the motion of a block attached to an ideal spring. The block can oscillate back-and-forth horizontally. Users can change the mass of the block, the spring constant of the spring, and the initial position of the block. You can then see the resulting motion of the block, as well as see bar graphs of the energy and plots of the block's position, speed, and acceleration as a function of time.

The Spring Motion 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_bu_reference_circle.jar file will run the program if Java is installed.
