INVESTIGATION: Create a method to accurately and reproducibly (?) determine the maximum downward force that can be exerted on a roll of toilet paper WITHOUT breaking it; and then calculate/predict the resulting maximum resultant angular velocity of that TP Roll.


  • Design a method to apply that force to the TP roll

  • Precisely apply that force

  • Measure the resulting angular velocity (how?)

  • Compare your theoretical/calculated initial values with your resulting experimental/actual values and appropriately explain any discrepancies.
