Day 44: Tug-of-War!
College-Prep Physics: We discussed the results from Wednesday’s friction lab:
What does the slope mean? How does the slope relate to the “grippiness” of the two surfaces?
Then we repeated the experiment with our shoes to determine the “grip factor” between our shoes and the tile. Then used the grip factor to extrapolate to how much friction there would be when we’re wearing our shoes.
Theoretically, the tug-of-war team that wins is the team with the most friction. So we used the friction calculations of the students who wanted to participate in the tug of war to determine the winning team.
Time to test our prediction!
