Siena College - General Physics 110 Having a “Ball” with Uncertainties Lab ● Do your values above seem reasonably close or significantly different in comparison to the averages reported by the class as a whole? How do you know? ● Would you expect every throw to have the same time-of-flight? Would you expect every person in the room to measure the same time-of-flight on any given throw? ● Is there a difference in asking what is the average time for the throws recorded by one student and what is the average time that all students record for one throw? If so, describe the difference(s). ● Do Caitlin and James have the same average time for their throws? Would you expect them to? Explain your thinking. ● Do Caitlin and James have the same standard deviation in their time for their throws? Would you expect them to? Explain your thinking. ● Did all the people in your group get the same average time? Or a better way of asking this question would be, are your answers consistent with one another? ● What may have contributed to uncertainties in your measurements? Identify as many sources of experimental uncertainty as you can. Scientific Ability Missing Inadequate Needs Improvement Adequate B7 Is able to identify a pattern in the data No attempt is made to search for a pattern. The pattern described is irrelevant or inconsistent with the data. The pattern has minor errors or omissions. The pattern represents the relevant trend in the data. G5 Is able to analyze data appropriately No attempt is made to analyze the data. An attempt is made to analyze the data, but it is either seriously flawed or inappropriate. The analysis is appropriate, but it contains minor errors or omissions. The analysis is appropriate, complete, and correct. G1 Is able to identify sources of experimental uncertainty No attempt is made to identify experimental uncertainties. An attempt is made to identify experimental uncertainties, but most are missing, described vaguely, and/or incorrect. Most experimental uncertainties are correctly identified. However, there is no distinction between random and experimental uncertainty. All experimental uncertainties are correctly identified. There is a distinction between experimental uncertainty and random uncertainty. 3
