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):

With just the TIMER program considered and only the machine’s limitations affected accuracy, I would say .0001 accuracy.

• 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 believe earlier clicking as fast as I could the times were within .005 of each other, so adding in the need for accuracy I’d estimate an accuracy within .05 seconds.

• 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):

The percent error would get smaller because the numbers used would be getting smaller and thus the uncertainty would be smaller.

• 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):

My ruler only went to millimeters so the accuracy was to .1 cm.
