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:

If the two events are spaced a fair amount of time between them, the TIMER program I think is very accurate. If the two events are very close together, the accuracy of the TIMER program drops drastically.

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

->->->->->->->->->->->-> answer/question/discussion:

For reasonable accuracy, I would think there would have to be at least 1-2 seconds between the intervals.

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

->->->->->->->->->->->-> answer/question/discussion:

The percent of error increases as the amount of time between intervals decreases.

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

->->->->->->->->->->->-> answer/question/discussion:

I am able to accurately measure the positions within about a .01 range of accuracy on the computer screen. The video however was very blurry when I paused to get my readings, so if I had any error it wouldn’t be the computer’s TIMER, but the quality of the video that is to blame.
