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:
Because of my own slow reaction time when clicking to start and stop the timer, I am less concerned about the accuracy of the timer itself than I am about human error. (My boys never let me man the stopwatch when they run track, and I am never a timer at my daughter’s swim meets!)
• What is the shortest time interval you think you would be able to measure with reasonable accuracy?
answer/question/discussion:
Based on my timer experiment, I would guess that the shortest interval I could measure with reasonable accuracy is about .1887 seconds.
• How does the percent error in timing intervals change as the time between the events gets smaller?
answer/question/discussion:
As the interval gets smaller, the percent error would get larger.
• How accurately are you able to measure the positions of the ball and the pendulum in the initial video?
answer/question/discussion:
I found it very difficult to measure the positions of the ball and pendulum in the video, so many of my numbers were just close estimates. I tried to pause the video at various times, but had trouble with blurry pictures, etc.

Please excuse me for being so late with this week's work. My family has been ill with the flu (myself included) and it has been impossible for me to work on school for about a week. I will be all caught up by Tuesday when the next assignments are due!
&#Good responses. Let me know if you have questions. &#
