Part III: Centripetal Force vs. Radius
In Part III, the velocity and mass are held
constant as the radius is varied. Lowering the
Force Sensor increases the radius. As the radius
increases, the “fixed mass” must be moved to a
matching radius to balance the rotating arm.
Again, centripetal force is measured by the Force
Sensor. Repeat the experiment at different radii
(i.e.vary the radius from 22 cm to 8 cm in 2 cm
steps). Use a graph or table to record the force at
the set speed. In DataStudio, make an editable
graph of the Force vs. Radius.
Note: If force readings do not appear in
DataStudio, check your sensor-to-interface
connections and setup in DataStudio. See Appendix A of this manual.
