Centripetal Force Apparatus

Model No. ME-8088

Experiment 3: Centripetal Force vs. Radius

Introduction

In this experiment, the velocity and mass are held constant as the
radius is varied. By lowering the Force Sensor, the radius increases.
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.

Setup

Follow the equipment setup instructions on pages 5-7 of this manual
and the Experiment Tips that follow. When you are ready to begin the
experiment, open the appropriate DataStudio file on the setup disk.
