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):

The timer programs times down to the 6th decimal place. While this is more precise than most other timers we could use we also have to relize that there will be error based on how quickly we press the button, and how effectively we observe the object needing to be timed.

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):

When constantly clicking the mouse the interval between clicks seem to ~0.15 seconds, so this is as close of an interval that we could accurately measure.

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 percert error has a greater chance of being higher as the intervals become 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):

The pendulum was measured witht he timer so it was measued using 6 decimal places. I then rounded it to the closest tenth of a second. This is becaue the timing weres based off of simple observation.

@&

The computer expressed the result to 6 decimal places.

If the computer measured time intervals in increments of 1/3 second, is could express intervals like .333333 second, .66666667 second, etc., but that would not mean that its measurements were accurate to 6 or 7 places.
