Experiment 2: Centripetal Force vs. Mass
Introduction
In this experiment, the radius and velocity are held constant as the mass is
varied. By adding additional drilled masses to the holder, the mass of the
system is increased. Equal amounts of mass must also be added to the “fixed
mass” to balance the arm as it rotates. Centripetal force is directly measured
by the Force Sensor.
Setup
Follow the equipment setup instructions on pages 5-7 of this manual
and the Experiment Tips below. When you are ready to begin the
experiment, open the appropriate DataStudio file on the setup disk.
