Answer the following:
How accurately do you think you can measure the time between two events using the TIMER program?
answer/question/discussion: ********* ********* Using a TIMER program, I believe I can measure time between two events fairly accurately. It will all really hinge on my ability to accurately trigger the start and stop of the TIMER. If I can discipline myself to do that correctly (or reasonably well), then I can reasonably gauge the time using the TIMER program.
What is the shortest time interval you think you would be able to measure with reasonable accuracy?
answer/question/discussion: ********* ********* Using the TIMER program, I believe I can measure down to the second with very good accuracy. I can measure down to the tenth of a second with fair accuracy. Anything past that is somewhat questionable.
How does the percent error in timing intervals change as the time between the events gets smaller?
answer/question/discussion: ********* ********* As the time between events gets smaller, the percent error in timing increases. If the starts and stops are where the majority of the error comes into play, then the % of that error will become smaller as more time elapses. Therefore, if we only measure a short amount of time, the % error will be higher then if we measure a longer amount of time.
How accurately are you able to measure the positions of the ball and the pendulum in the initial video?
answer/question/discussion: ********* ********* Not very. It was difficult, especially at shorter lengths, to ensure the pendulum was swinging at roughly the same length for period. It appeared this was the same in the video. It is difficult to gauge start position and period length when using merely the human hand.
This should nevertheless be quantified.
