Two-body motion
Use the left mouse button to mark the first body and the right mouse button to mark
the second body.
You can mark two-body motion in two ways: simultaneously or consecutively. In the
simultaneous method you mark the two bodies alternately on every step of the
marking process. In the consecutive method you finish marking the whole motion of
the first body and then repeat the process with the second body.
