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 think that the TIMER program itself is very accurate. Any inaccuracies come from human faults. Therefore, I think that the time between two events can be measured very accurately with the TIMER program.
• What is the shortest time interval you think you would be able to measure with reasonable accuracy?
answer/question/discussion: ->->->->->->->->->->->-> : The shortest time interval that you would be able to measure with reasonable accuracy is .00001 second because the TIMER program can read to .000001 second, but since some human error will always occur, it cannot be accurate to that place.
• How does the percent error in timing intervals change as the time between the events gets smaller?
answer/question/discussion: ->->->->->->->->->->->-> : As the time between the events gets smaller, the percent error increases.
• How accurately are you able to measure the positions of the ball and the pendulum in the initial video?
answer/question/discussion: ->->->->->->->->->->->-> : In the initial video, it is difficult to measure the positions of the ball and the pendulum because a) the ruler is blurry and b) there is no instruction regarding which point on the ball or pendulum to measure. I would say that it is possible to measure the positions at 95% accuracy.

Very good work. Let me know if you have questions.
