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: Based on earlier use of the TIMER program, it seems to only work accurately to the nearest .01. After that, it seems to repeat the decimal places.

• What is the shortest time interval you think you would be able to measure with reasonable accuracy?

answer/question/discussion: The shortest time interval to measure with reasonable accuracy may be a little less than half a second. Factors that may limit the accuracy beyond this is the limitations of the TIMER program, and human inconsistency in timing.

• How does the percent error in timing intervals change as the time between the events gets smaller?

answer/question/discussion: The percent error greatly increases as the time between the events gets smaller. For example, a .1 second error would be a much greater percentage in a 1 second interval then in would in a 10 second interval.

• How accurately are you able to measure the positions of the ball and the pendulum in the initial video?

answer/question/discussion: There was enough time between pendulum swings so that the accuracy of the TIMER program wasn't much of a factor. However, trying to time at the right moment was hard to do and be accurate with.
