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: ->->->->->->->->->->->-> : The Timer program measures time fairly accurately. Instead of giving the exact intervals it rounds the intervals to the nearest set interval time.

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

answer/question/discussion: ->->->->->->->->->->->-> : The shortest interval would be .0001 seconds because it is accurate up to .0001 digits.

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

answer/question/discussion: ->->->->->->->->->->->-> : The percent error increases as time between events gets smaller. For example, if your time interval was .0052 seconds with an uncertainty of .0001 then the interval has a percent error of plus or minus 1.9%. But, if you had a larger interval, the percent error would decrease. For example, if your interval was 500 seconds with an uncertainty of .0001 then the percent error would be around 0%.

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

answer/question/discussion: ->->->->->->->->->->->-> : You are not able to measure the positions of the ball and the pendulum accurately because it was very difficult to see the numbering and the marks in between.
