This example demonstrates:
- The animation of spring and damper components
- A body can be freely moving without any connection to a joint.
In this case body coordinates are used automatically as
states (whenever joints are present, it is first tried to
use the generalized coordinates of the joints as states).
- If a body is freely moving, the initial position and velocity of the body
can be defined with the "Initialization" menu as shown with the
body "body1" in the left part (click on "Initialization").
