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): Fairly accurately. The only discrepency is that the first click time is not 0.000 seconds, it is however much time has passed since the TIMER loaded. So you have to measure how far from the first time the second time is, not how far from 0.000.

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): Reasonably within a second. Any smaller unit of time would be too inconsistent to call it accurate.
#$&*
How does the percent error in timing intervals change as the time between the events gets smaller?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line): With more events and smaller intervals the percent error would slowly get smaller.
#$&*
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): Fairly accurately. There were times when I made a mistake in clicking.
