A bicycle wheel that was initially spinning freely was placed in contact with
a rough surface and a digital film was made of its motion. Using Tracker
software for video analysis, we obtained the velocity vectors for several
points on the wheel, in the frame of reference of the laboratory as well as
in a relative frame of reference having as its origin the wheel’s center of
mass. The velocity of the wheel’s point of contact with the floor was also
determined obtaining then a complete picture of the kinematic state of
the wheel in both frames of reference. An empirical approach of this sort
to problems in mechanics can contribute to overcoming the considerable
difficulties they entail.
