UGA PHYSICS 1111 LAB FINAL EXAM LATEST 2026 UPDATED
QUESTIONS AND VERIFIED 100% SOLUTIONS (2026/2027) |A+
GRADED |GUARANTEED PASS
LAB 1 INTRO LAB EXCERCISE
-Study Error
-Precision
-SIG FIGS
-Construction of Graphs
-How to use air track measurement system for motion exercises - Answers -...
LAB 1: error & accuracy & %error & diff - Answers --Error: diff between value of physical
quantity determined by experiment and true value
-Types of error may occur during an experiment: experimentalist not take the time to be as
accurate & detailed
-Accuracy: percentage diff or absolute diff
-Percentage Error = (Estimated- Actual)/ (Actual) x 100
Percent difference= | E1- E2 | / 1/2(E1 + E2) x 100
LAB 1- precision - Answers --related to way u carried out measurements & how u reported ur
results
-precision of a number indicated by # of sig figs used
LAB 1: Sig Figs - Answers -leftmost nonzero # = most sig
rightmost nonzero # = least sig

,LAB 1: The result of a multiplication or division should have how many significant figures? -
Answers -As many as the factor with the least amount of figures
LAB 1:
When excess digits are dropped from a number, the last digit retained should be - Answers -
ROUNDED
LAB 1: GRAPH PART: - Answers --(the measured/dependent variable on y-axis and (set or
independent variable on x axis
-prediction is correct=results should be straight line w slope C
equation for straight line: y =(slope)x + (intercept)
LAB 1: graph continued - Answers --best line of fit: line that agrees w/ trend of the plotted data
points while minimizing error
-slope is evaluated: drawing right triangleABC & THEN DETERMINE LENGTH OF THE SIDES AB
AND BC-slope is ratio of bc to ab
LAB 1: apparatus - Answers -apparatus: studies straight line motion

, LAB 1: The Air Track - Answers --no friction & air track level=air track not move
-not leveled=gilder will move back n forth and it could be adjusted by the bolt on the bottom
-ours wasn't so we adjusted bolt and made it lower so the glider would remain in place
LAB 1: air track - Answers -when track is lvl, push glider and watch motion
-overtime glider does slow down & eventually stops. (friction reduced but NEVER ZERO)
LAB 1: air track continued
sources of friction slowing glider down - Answers --air resistance
-friction from hitting bumpers
lab 1: air track continued
what can you to cause the glider to accelerate even after you let go (ignore friction) - Answers -
adding more air once the glider is in motion and tilting air track
lab 1: air track continued
what can the yellow ruler stip on air track be used to measure? - Answers -measures distance
between two successive placements on the glider
