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 believe with the right hand/eye coordination, the TIMER program can be pretty accurate.

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

answer/question/discussion: Probably within about +/- .25 of a second. Is that high? Or maybe low? I’m thinking that anything quicker than that wouldn’t be accurate due to hand/eye coordination in knowing what exact point to measure and the reliability of my finger pressing the button.

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

answer/question/discussion: the percent error will probably go up as the time between the events get smaller because it’s harder to judge things quickly.

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

answer/question/discussion: due to the quality of the video, not very accurate. I wasn’t able to see the numbers on the ruler at all. I noticed the black mark so I could probably get within .5 in or so.
