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

answer/question/discussion: ->->->->->->->->->->->-> : Reasonably accurately, as far as seconds and even tenths or hundredths, but not much beyond that.

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

answer/question/discussion: ->->->->->->->->->->->-> : Probably within a few tenths of a second due to my inability to click/react immediately in response to whatever situation on which I’m trying to collect data.

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

answer/question/discussion: ->->->->->->->->->->->-> : As the time between events decreases, the percent in error increases.

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

answer/question/discussion: ->->->->->->->->->->->-> : Not very accurately. I have a good idea or general picture of the times, but my results aren’t precise.
