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: ->->->->->->->->->->->-> : I believe that the TIMER program will measure time between two events very accurately. The only thing that I really believe will cause a slight problem is our reaction speeds. By the time we process the thought to click the timer button and actually click the button, we have lost a small amount of time. So, I really dont think that we (not the TIMER program) can get the exact time measurement, but we can get pretty close.
What is the shortest time interval you think you would be able to measure with reasonable accuracy?
answer/question/discussion: ->->->->->->->->->->->-> : I would have to say about anything .25seconds and higher apart.
How does the percent error in timing intervals change as the time between the events gets smaller?
answer/question/discussion: ->->->->->->->->->->->-> : The percent error changes quite a bit because we have more room for error when the time events get smaller.
How accurately are you able to measure the positions of the ball and the pendulum in the initial video?
answer/question/discussion: ->->->->->->->->->->->-> : I believe that I was able to measure the positions relatively accurately. I had a pretty good idea where each mark was. The only problem was that there was a kind of parallax because the tape measure was a few inches behind the actual ball and pendulum.
