Question

First, each partner should time one complete swing. Write your measurement of the period (with uncertainty) below, but do NOT show your mull to sour partners Your measurement: T= 10) Once each has recorded his/her measurement, cops your partners' measurements below: Q: Do all your measurements fit within the range predicted by your uncertainties' If not. What should you do? 11) Finally, take one measurement of the total time required foe 10 swings: From this value. Compute the period T, propagating uncertainties: How does the uncertainty in T computed in step II) compare to the uncertainty in timing a single swing?

Explanation / Answer

uncertainty in T computed in step 11 = 2 * 3.14 * sqrt(0.382/9.8)

                                                           =   1.24 sec

=> uncertainty in T timing a single swing = 2 * 3.14 * sqrt(0.191/9.8)

                                                          =   0.876 sec
