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: ->->->->->->->->->->->-> (start in the next line):

If the two events are reasonably far apart, I think the difference between them can be accurately measured to 7 decimal places because the timer has digits out that far.

That doesn't mean it's accurate to all the displayed digits.

• What is the shortest time interval you think you would be able to measure with reasonable accuracy?

answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):

I think the shortest time interval the TIMER program can measure with reasonable accuracy is .01 (one hundredth of a second).

#$&*

• How does the percent error in timing intervals change as the time between the events gets smaller?

answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):

The percent error gets larger as the time intervals get smaller because the uncertainty stays the same, but as it’s compared the interval, it is a larger fraction or percent of it, which means the percent error increases.

• How accurately are you able to measure the positions of the ball and the pendulum in the initial video?

answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):

I was able to measure the positions of the ball and pendulum in the video to within 1 inch (+/- 1 in).
