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 itself is pretty accurate, but the human interference is what makes it less accurate. I believe that it is 80% accurate to measure the time between two events using the TIMER program.

• 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 that the shortest time interval that I could accurately measure would be .1.

• 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 in timing intervals changes when the time gets smaller by getting smaller also. The percent error is based upon the last digit of a number.

• 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):
You are able to be pretty accurate on the position of the ball in the initial video by about 1/2 of an inch. This is because the video’s picture quality is at times blurry and thus lessen the accuracy.
