We are representing the fall of an object onto a lever that causes the movement of another object.

With the "m.bl" and   "m.re" controls you can select the mass of each object.

The initial height of the blue object can be selected by clicking on it and dragging it to the right position.

You can also select the height reached by the red object the same way.

The mechanical energy data describe the system except when the objects are still on the lever.

Always press "init" before an observation.
