Lab II Notes Week of 2008.09.22 Lab II: The Freely Falling Body This lab asked for some simple data collection followed by a number of calculations. Here is what I was looking for. Quiz • Average velocity for an interval, equal to the velocity at the time midpoint of the interval, is ∆x/∆t. • Acceleration for an interval is ∆v/∆t. Analyses • From part A, a v vs. t plot. • From v vs. t and from two sections on the tape, the average value of a. • Comparison between your a and the official value of g. • Average v for the whole tape compared with instantaneous v at the time-midpoint. Best with an algebraic proof that they should be equal, but I didn’t take off points for that. • Based on a and v0, predictions compared with data for x(t) vs. t. Questions • Discussion of other forces affecting a. • Discussion of constancy and validity of a as a value for g. • Discussion of the effect an initial downward push would have (the correct answer is that there would be no effect on g). 1
