Newton's Third Law With Pasco Force Platforms
Demo Description
Set up Pasco interface and two force platform sensors to get high tech Data Studio verification of the third law for dueling students holding platforms and pushing against each other.

Instructions
The
first photo shows the two force platforms and the interface.
The second photo gives a closer view of a platform.
Open the Third Law_Large Data Studio Activity File in the Physics folder under Data Studio, to get a display with graphical outputs of each sensor .
Have two students hold the sensors by the handles with their planes vertical and bottom surfaces together. A pushing "duel" will show equality of force magnitudes on each student. (Caution duelers to use moderation and perhaps alternately let each other fall back and go forward a little.)
