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 program is pretty accurate. Although, I think that it is probably off +- .05 seconds.

• 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 think it would probably be about .1 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 increases as the time between events get 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):

I had to take a few looks at the video before I was able to determine the positions. I think that I was probably on target +- .5 cm.
