8. The figure below represents an overhead view of the rotating mass. For each of the 4 points, draw
the direction and relative magnitude of the force.
Demonstration Using a Force Sensor
Set up the Discover Centripetal Force Kit as instructed. Replace the hanging mass with a Force Sensor. The
measurements of the Force Sensor are roughly equal to the centripetal force. Have an assistant hold the
sensor. Move it up or down to change the radius.
Demonstration Using a Newton Spring Scale
Set up the Discover Centripetal Force Kit as shown in the Classical Centripetal Force Lab. Replace the
hanging mass with a Newton Spring Scale. The measurements of the Newton Spring Scale are roughly
equal to the centripetal force. Have an assistant hold the sensor. Move it up or down to change the radius.
This method allows the student to "feel" the changing in the centripetal force.
