1M40.50 - Yo-Yo's and Maxwell's Wheel - Speed of Translation
Video and Editing Credit: Jonathan M. Sullivan-Wood.
Attach the cross rod with the Maxwell's wheel to the support assembly and make sure that it is secured tightly. Hang the support assembly from the Newton scale and the scale from the special hook clamp. Add 2 kg + 4 lbs of mass to the support assembly. This combination has been picked to give a good time scale for the spring deflection. The Maxwell's wheel will only appear to be heavier at the bottom of its stroke in relation to its rest mass. It will show no apparent affect at the top of its stroke due to inherent physical construction and parameters.
The Maxwell's wheel can also be used to measure the speed of translation using a photogate, motion sensor, or rotary motion sensor.
The strings of the yo-yo's may have to be twisted and wound several times before they work well. As usual practice makes perfect.
