SHM using a Mass-spring

This is a teacher or student controlled, realistic 3d simulation of an investigation into Simple Harmonic Motion (SHM) using a mass-spring system.  The investigation will allow the determination of the spring constant.

Different weights can be placed on the spring and then given an impulse.  A timer is used to determine the period of oscillation.

The user has control over the weight on the spring, the position of the fiducial marker and the timer controls.  The user is free to move anywhere within the laboratory in order to interact with the apparatus.
