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):
One could take the time of the second punch and subtract the first one from that one. That is about as accurate as one can get. However, know that one would have to do this between each interval.

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):
If I measured it myself, it would have to be at least over one second. I couldn't measure less than one 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):
Some answers show up over and over again as the event is taking place. The percent error keeps getting smaller and smaller, but also increases in how many decimal places are shown.

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):
It takes more than one time just watching the video, but after a couple tries I was able to get it within at least .3 seconds.
