The problem:
Answer the following:
*
How accurately do you think you can measure the time between two events using the TIMER program?
answer/question/discussion: ->->->->->->->->->->->-> scussion: Given human error in reaction time and in determining when the beginning/end of those two events were, I'd say 0.1ish accuracy, but if we're just talking about the timer program without human error, I think it was accurate to about .0001.
*
What is the shortest time interval you think you would be able to measure with reasonable accuracy?
answer/question/discussion: ->->->->->->->->->->->-> scussion: Again, for me, I'd say .1, maybe .5 or 1 second if I'm particularly sluggish.
*
How does the percent error in timing intervals change as the time between the events gets smaller?
answer/question/discussion: ->->->->->->->->->->->-> scussion: The percent error in timing intervals gets much higher as the time interval between events gets smaller, because the error (say .1 human error) stays the same but the number measured gets smaller (so .1 s/100 seconds has less % error than .1 sec/10 seconds).
*
How accurately are you able to measure the positions of the ball and the pendulum in the initial video?
answer/question/discussion: ->->->->->->->->->->->-> scussion: I think I was able to measure the tape/pendulum accurately to the nearest inch.
