Investigating elastic force

This week our investigations will lead us to thinking about forces. Today, we looked at the force needed to stretch a rubber band. There are 2 questions we want to answer:

1. What happens to the force required to stretch a rubberband when the stretching distance is doubled?
2. Based on the graph, is there a relationship between the force needed to stretch the rubberband and the distance it stretches?

Please have your data graphed for tomorrow's discussion.

Also, HW for the week has been assigned today. See Class Info for a link to the assignments. Keep in mind that work not finished in class may be assigned as additional homework.

QUIZ WEDNESDAY! Study parts of a battery, energy forms and transformations.
