'''''Important Setup Notes:''''' 
 *  N/A


'''Setup and Procedure:''' 

 1. Place the vertical mounted bike wheel on the table as shown.
 1. Apply a small torque &tau; = r x F onto the wheel to give it a rotational speed.
 1. Note the different speeds of the two markers as the spin about the same axis but at different radial distances.

'''Discussion:''' 

The two red markers are attached to a rigid body spinning about an axis. Thus, the two markers also have the same rotational frequency ω. However, the two markers will have different tangential speeds. This speed is v = ω * r where r is the distance of the marker from the axis of rotation. Thus, the further out the marker from the center of the wheel, the faster it will be moving thought it will always have only one rotational frequency.
