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):
With just the TIMER program considered and only the machine’s limitations affected accuracy, I would say .0001 accuracy.

• 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 earlier clicking as fast as I could the times were within .005 of each other, so adding in the need for accuracy I’d estimate an accuracy within .05 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):
The percent error would get smaller because the numbers used would be getting smaller and thus the uncertainty would be smaller.
@&
The uncertainty in the TIMER program doesn't get smaller. If anything, for short time intervals it gets bigger.
Either way, the percent uncertainty gets bigger when the time interval gets smaller.

• 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):
My ruler only went to millimeters so the accuracy was to .1 cm.
