Motion of Centre of Mass

Applet shows the motion of the centre of mass of a dumbbel shaped object. The red and blue dots represent two masses and they are connected by a massless rod. The dumbbel's projection velocity can be varied by using the velocity and angle sliders. The mass ratio slider allows shifting of centre of mass. Here m1 is the mass of the blue object and m2 is the mass of red object. Check boxes for path1 and path2 can be used to display or turn off the paths of the two masses.

Please wait till the applet loads. It should not take long. When the applet is loaded, you would see words "Run the Applet" in the box below these lines. Click anywhere on the inner box and another window opens up in which the applet can be run.
