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.
