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):
The timer program is accurate to about 0.01 seconds…. I think.

• 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):
Based on the timer program information I’ve gathered so far and the time intervals between clicks of a mouse for example, the shortest time interval measurable with reasonable accuracy, is 0.001 seconds.

• 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):
If I’m interpreting the question correctly, as the time between events gets smaller how does the percent error change? A the time intervals get closer together, I think they become more accurate. If they are 0.001 seconds apart, then they cannot have a percent error of 0.1 seconds. I think. This means the percent error would decrease as they time intervals get closer together.

• 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):
Personally, from what I can decipher from the video, the position of the ball (tape) and the pendulum can be accurately measured within about half an inch when the video is stopped and you measure from the marked positions on the measuring tape.
