The problem:

Answer the following:

How accurately do you think you can measure the time between two events using the TIMER program?

I believe one of the big issues in the timer program is not being able to account for

human error or the time that it takes to trigger the mouse button. So if you could

measure the exact amount of time that it takes to trigger the mouse and took that

away from the actual recordee time then it would be more accurate. But, I believe

it does well enough for what we have been using it for.

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

Again, I would have to say that the shortest time interval would still depend

entirely on human intervention. So, if you determine the reaction time it took for

a person to click the mouse button, I believe that then the timer program would be quite accurate, within tenths of a second.

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

As the timing intervals are smaller the percent error is much greater, there is a smaller room for accuracy.

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

I believe that you could only be within 1-2 inches either way with the ball. It

still a judgement call to, it was visually hard to see the markings on the tape

line. I was still able to take a reasonable measurement that I believe was fairly

accurate.
