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 trust the program itself more than I do my own clicking to start and stop the timer, that is where the biggest error will occur.

• 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):
Somewhere around 0.5 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):
I think the % error gets higher and higher as the time intervals get smaller. It is more difficult to accurately measure tiny fractions of a second than it is to measure hundreds of seconds, minutes.

• 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):
Its very difficult to be accurate with the video because it is quite blurry. I think the video itself is more at fault here than the timer program or human error would be.
