Spring & Mass


The applet shows two masses attached to a spring oscillating on a  smooth horizontal surface. The spring is initially in an elongated state and pressing start button releases the masses. Graphs of position vs time of the two masses are shown. Notice that when the masses are unequal the frequencies of oscillations are same but the amplitudes differ. A gray vertical line shows the x coordinate of the CM of the two masses.
