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):
I believe that I can accurately measure the time between the two events by .01
#$&*
What is the shortest time interval you think you would be able to measure with reasonable accuracy?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
The shortest time interval I think would be .01.
#$&*
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):
I believe the reason that the percent error in timing intervals change as time between the events gets smaller as we get smaller and smaller the error is less than as if it was a larger interval.

Suppose your uncertainty in measuring time intervals is 0.1 second.
What then would be the percent uncertainty when measuring an interval of 5 seconds?
What would be the percent uncertainty when measuring an interval of 2 seconds?
What happens to the percent uncertainty as the time interval gets shorter, and why is this the case?

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 believe I can accurately measure of the position by + or - 3.

Your answer regarding percent uncertainty needs a little more justification.
I've inserted a few questions about how the percent uncertainty changes. As a revision, can you answer those questions?
