The EJS Quartic Oscillator model displays the motion of a bead moving without friction along a horizontal rod, while tied to two symmetric springs. Both the motion of the masses and the phase space plot are shown in the simulation. The natural length of the springs can be changed via textboxes. (less)

Spinning Hoop Model

The EJS Spinning Hoop model displays the model of a bead moving ... (more)

The EJS Spinning Hoop model displays the model of a bead moving along a hoop which is spinning about its vertical diameter with constant angular velocity ?. Friction is negligible. The simulation displays the motion of the bead as well as a plot of angle vs. time for the bead. The angular velocity of the hoop and the starting angle of the bead can be changed via sliders.

Symmetry Breaking on a Rotating Hoop

Symmetry Breaking on a Rotating Hoop

The Rotating Hoop Launcher package shows the dynamics of a mass that ... (more)

The Rotating Hoop Launcher package shows the dynamics of a mass that is constrained to move on a rotating hoop. The rotating hoop model is an excellent mechanical model of first- and second-order phase transitions. Although the minimum of the potential energy curve corresponds to the bottom of the hoop at low rotation frequency, a spontaneous symmetry breaking (cusp catastrophe) occurs as the frequency is increased. This package presents the theory, a demonstration, and an Easy Java Simulation (EJS) of this experiment. The package was presented at the NC Section of the AAPT Spring 2008 meeting. (less)
