Suggested Experiments
Experiment 1: Centripetal Force vs. Velocity
Introduction
In this experiment, you will vary the velocity by changing the voltage
to the electric motor as the centripetal force is continuously measured
by the Force Sensor. The radius and mass are held constant as the
velocity is increased.
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.
