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 that I can measure them fairly accurately. Probably between .25 and .5 sec.

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

answer/question/discussion:

I think I could measure 1 sec. fairly accurately, I think that I could measure something a little smaller, but I don’t know how accurate it would be.

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

answer/question/discussion:

The percent error grows as the time intervals get smaller, because there becomes less room for error. Ex. If you were off by 1 sec. out of 100 sec. it is only 1 percent, but if it is 1 sec. out of 10 sec. it is 10 percent.

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

answer/question/discussion:

I think that I was able to measure it fairly accurately, but being able to pause the video helps.
