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):
Within a hundredth of a second. Any shorter length of time seems a little too programmed with the timer. It doesn’t seem to differentiate numbers much when it comes to something that quick.

• 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):
probably one tenth of a second
#$&*
• How does the percent error in timing intervals change as the time between the events gets smaller?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
the percent error increases as the intervals become smaller
#$&*
• 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):
not very well at all because the video is very blurry, I can probably estimate within .5in just going by the lines on the ruler. For instance, all the darker lines are complete inches, so I can estimate the distance between two neighboring lines.
