TP LAB #2 PURPOSE: How accurately can you account for experimental error? TO DO ITEMS: 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 Determine a method to calculate the expected angular velocity of that TP Roll based on that data Determine a method to calculate the expected angular momentum of that TP Roll based on that data Investigate your error and account for that error mathematically and through further investigation/experimentation (see below). Report your findings in a Tabloid Article format as determined by the class... now. Then: Design a method to apply that force to the TP roll Precisely apply that force Measure the resulting angular velocity (how?) Measure the resulting angular momentum (how?) Compare your theoretical/calculated initial values with your resulting experimental/actual values and calculate the % error. Investigate your error and account for that error mathematically and through further investigation/experimentation. For Example: Let's say we were conducting an investigation to determine which make/model car get's the best gas mileage. We determined that the Toyota Prius achieved the highest gas mileage of all vehicles tested at 43.5 mpg. Upon conducting further research we found that the ACTUAL gas mileage for a Prius was 49.8 mpg. We calculate the error to be We investigated further and found out our car had a small hole in the gas tank that was dripping gallons of gasoline per trial. That loss of gallons of gasoline would account for a loss of miles per gallon which would account for of our error.
