Sample Lab ReportThis is an example of a well-written report from thePHYS 111 or 112 lab. Asexplained in the lab manual, it contains only the significant details of the experiment,the analysis and some conclusions. Particularly pertinent features are called out inthe marginal notes. Background material is not needed because the reader is assumedto have the lab manual available.This document is typed and uses computer-drawn figures to facilitate posting on theweb. You may prepare any or all portions of your reports by hand, as convenient, butbe sure the text is legible and figures are clear. Graphs should be done on graphpaper or by computer, not as rough sketches.Physics 11xExperiment 1,947a The large amplitude pendulumby: I. M. Studentpartner: A. BumblerFebruary 30, 2010We are trying to measure the amplitude dependence of the period of a simplependulum. By extrapolating to zero-amplitude we determine g.ProcedureWe measured the period of a simple pendulum of known length as a functionof release angle.1. Rather than measure the pendulum length directly, we used a meter stickwith caliper jaws to measure from the support to the bottom of thependulum ball. We measured the diameter of the ball with calipers, andfound the distance from the support to the center of the ball by subtraction.2. To get the angle we measured the distances s and d shown in the sketchand used the relationsin θ = d/sThis seemed more accurate than using the small protractor provided.sdθShort statement ofintentionProcedures aredescribed briefly,without much detail ofthe apparatus.3. The actual period was measured for the first swing after release, using aphotogate timer in pendulum mode placed near the bottom of the trajectory.Datatotal length = 0.757 m ± 0.002 mball diameter = 0.0256 m ± .0005 mpendulum length = 0.744 m ± .002 mstring length s = 0.731 m ± .002 mThe period was measured three times for each angle and averagedd (m) T (s) aver T (s) θ (rad).164 ±.002 1.7326, 1.7330, 1.7328 1.7328 .226.104 1.7294, 1.7296, 1.7297 1.7296 .143.043 1.7286, 1.7288, 1.7288 1.7287 .059.226 1.7380, 1.7381, 1.7382 1.7381 .314.385 1.7606, 1.7609, 1.7609 1.7608 .555.292 1.7460. 1.7460. 1.7462 1.7461 .411We used Graphical Analysis to plot T vs θ2 and fit a straight line. The straightline is an acceptable fit, showing that the relationshipT = T0 (1 + θ2/16)is reasonable. The graph is attached.To get g we use the results from the program:intercept = T0 = 1.728 ± .0002 sslope = T0/16 = 0.108 ± 0.001 s => T0 = 1.73 ± .02and the pendulum equation T0= 2πg / lto find g = 9.84 m/s. The length of the pendulum is the largest uncertainty, at0.3%, so it determines the uncertainty in g = 9.84 ± 0.03 m/s.CommentsOur results are consistent with the claims in the lab manual. The value of g isabout the same as we found in the free-fall experiment.Single items of dataare just listed, withuncertainties.Tables compactlydisplay a set of data.Explain calculations,but don’t showarithmetic.Be sure yourconclusions agreewith your data.Comparison to“accepted” valuesnot usuallyappropriate.0.40.30.20.10.01.721.731.741.751.761.77Large amplitude pendulumtheta^2 (rad)Period (s)Axes are labeled, withunits.
