PHYS 2142 Lab #3 - Determination of 'g' via Picket Fence Data Sheet [Virtual] Name: Kristopher Carrasco Data Table (from page 4 of lab notes) : Trial 1 2 5 Acceleration 8 . 927 (m/ s') 9. 761 9. 706 10.240 9. 691 9. 923 1) Calculate the Mean Acceleration value (see example on page 2 of lab notes) (Note: You have six measurements (trials) ]: Mean = Sum Measurements Number of Trials 2) Calculate the Uncertainty value (see example on page 2 of lab notes) : Minimum Maximum Acceleration (m/ s?) Maximum - Minimum 2 2 3) Express the Result as Mean + Uncertainty (see example on page 3) : gep = Mean + Uncertainty = m /s 4) Calculate the Percent Error (see example on page 3 of lab notes) : 8 exp - 8 me *100 *100 % error = 9 true Note: The "True" g-value for the Chicago area is 9.804 m/s? 5) From your Percent Error Answer, rate your result as: Excellent (< 14), Good (14 to 54), OK (5 to 10%), and Bad (> 108)
