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):
Given all other things equal and accurate, I believe that I can measure the time between two events to within .1 second of each other using the TIMER program.

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 believe that given my human limitations, the shortest time interval that I would be able to measure with reasonable accuracy would be .1 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 in timing intervals goes down as the time between events gets smaller. If the timed events are more precise, then the percent error is less.

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 felt like I was really only able to accurately measure the position of the ball and the pendulum in the initial video to about 1/2 inch.
If the video was high definition or closer to the ruler then I might could have been more accurate in my estimations.
