Coupled Oscillations

This applet shows two blocks of equal mass connected to rigid supports by stiff springs (white). The two masses are also connected by a weak spring (red) to each other. Initially the left mass is drawn to the right holding the right mass at its equilibrium position. Pressing start button releases this mass and the oscillations begin. It is interesting to observe the transfer of energy from one mass to the other through the coupling provided by the red spring. The transfer is faster when the spring constant of the red spring is greater. The graphs at the bottom show displacement of either mass versus time. Click anywhere in the applet area  to switch between the graphs of either left mass or right mass.
