Three Scales
There are three scales.
The one on the right (navy shirt) indicates a 10 N force to the right ... +10 N.
The one on the left (green shirt) indicates a 10 N force to the left ... -10 N.
What will the scale in the middle read?
What other mathematical aspects of this caught your attention? What do you wonder about the situation?
