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: ->->->->->->->->->->->-> (start in the next line):

Taking into account all aspects that contribute to the accuracy of the program, I think the timer program is efficient in measuring all experiments we have done thus far. There is a rounding aspect but I think some of the other factors would cause more of an error than the program itself.

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

answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):

I feel comfortable measuring accurately to 1/4second with the program.

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

answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):

Percent error would increase as time intervals decreased as there is less and less room for error. Even a small error is magnified with a small sample.

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

answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):

I was able to measure within one-half inch on the video and feel comfortable doing so.

Exactly how accurate is the timer program?
