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):

 To about .1 seconds, due to human error

 

#$&*

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):

 About half a second, because of the time it takes a human to recognize events and hit the button.

 

#$&*

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):

 As the time interval gets smaller, a given error, say .01 seconds, makes up a larger percentage of the measured time.

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):

 Within 1 in, any more accurate and the speed of the camera and motion blur becomes an issue.
