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):
Depending on click times, and a previous exercise, I think i can measure the time between two events by about +-0.1 seconds.

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 I would be able to measure with reasonable accuracy would be at a minimum of +.20 seconds

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'm not to sure, ???? is it because as the time between events gets smaller, there is a smaller average ratio ????

@&
You would want to consider the ratio of the error to the interval, which would involve dividing the error by the interval. The same error with a shorter interval will give a greater ratio, and a greater percent error.

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):
From what I remember, it was hard to see the measurement behind the ball in the initial video. So I based my measurements with an uncertainty of about 1 inch.
