10. Hypothesis: Which group member’s SHOES will require the most Newtons to pull? Why do you think so? Which SURFACE will require the most Newtons to pull a shoe across? How do you know? What will happen when you add mass to the shoes? Name of Group Member:Style of Shoe:# of Newtons Required to Pull on Blue Carpet # of Newtons Required to Pull on Tile Floor no extra mass + extra mass no extra mass + extra mass Now! Decide group member and which surface required the MOST Newtons and circle the person’s name. Pick one group member to add the group member’s date whose shoe required the highest number of Newtons to pull to our class chart.
