EXAM
QUESTIONS AND
ANSWERS
LAB 1 INTRO LAB EXCERCISE
-Study Error
-Precision
-SIG FIGS
-Construction of Graphs
-How to use air track measurement
system for motion exercises - answer
...
,LAB 1: error & accuracy & %error &
diff - answer -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= (value 1 - value
2/ ((value 1 + value 2)/2)) * 100
LAB 1- precision - answer -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 - answer leftmost
nonzero # = most sig
rightmost nonzero # = least sig
LAB 1: GRAPH PART: - answer -
measured/dependent variable on y-
axis
-set or independent variable on x
axis
-prediction is correct=results
straight line w slope C
-equation for straight line: y
=(slope)x + (intercept)
LAB 1: graph continued - answer -
BEST LINE FIT: line agrees w/ trend
of plotted data points
-SLOPE EVALUATED: drawing right
triangleABC & THEN DETERMINE
, LENGTH OF THE SIDES AB AND BC-
slope is ratio of bc to ab
LAB 1: apparatus - answer
apparatus: studies straight line
motion
LAB 1: The Air Track - answer -air
track level w no friction=air track not
move
-not leveled=gilder will move back n
forth and it could be adjusted by the
bolt on the bottom
LAB 1: air track - answer when track
is lvl, push glider & watch motion
-overtime glider does slow down &
eventually stops. (friction reduced
but NEVER ZERO)
