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):
I believe that through careful experimenting I should be able to time events to an accuracy of .1 sec. This is because we’ve already found out that the timer program has an accuracy of only .1 sec.

• 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):
Again the accuracy would only be to about.1 seconds due to the accuracy of the timer program.
#$&*
• 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 will go up due to the limitations of the timer program.

• 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 physical limitations are in 2 factors. The first limiting factor is in the timer, and the second limiting factor is in the frame speed capture of the video. The most accurate information is that we can determine the count of .1 seconds for the event to take place.
