Grade 745 min

aligned to 1.a Develop A Model To Describe Interactions Between Two Objects As They Collide And Show The Changes That Occur In The Structure Of Both Objects When One Object Is Damaged As A Result And Also When Neither Object Is Damaged As A Result. 1.b Ask Questions That Arise From Observations Of Collisions Between Two Objects In Order To Seek Additional Information About Factors (causes) That Might Affect The Outcome Of Such Collisions.

Learning Objective

I can explain how contact forces cause changes in the structure of objects during collisions.
