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.
