Unformatted text preview: cm (see Figure 12.2). We conclude that the top of the wheel moves twice as fast as the center and the bottom of the wheel does not move at all. Figure 12.2. Motion of wheel is sum of rotational and translational motion. An alternative way of looking at the motion of a wheel is by regarding it as a pure rotation (with the same angular velocity [omega]) about an instantaneous stationary axis through the bottom of the wheel (point P, Figure 12.3). Figure 12.3. Motion of wheel around axis through P....
