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: ->->->->->->->->->->->->
I believe I can measure time about 98% accurate between two events. The 2% I would say would be the finger clicking exactly at the end of the trial. Overall I think I will be pretty accurate and realistically one hundredth or thousand of a second will not affect the final results that much
• What is the shortest time interval you think you would be able to measure with reasonable accuracy?
answer/question/discussion: ->->->->->->->->->->->->
I think I can get reasonable accuracy to a hundredth of a second within something that is a half second. Anything after that is questionable, but will not affect the results that much.
• How does the percent error in timing intervals change as the time between the events gets smaller?
answer/question/discussion: ->->->->->->->->->->->->
I would say the percent error increases as the intervals become shorter because there is less of a error window that you are working with.
• How accurately are you able to measure the positions of the ball and the pendulum in the initial video?
answer/question/discussion: ->->->->->->->->->->->->
I can measure the positions of the ball and pendulum reasonably accurate possibly off in terms of tenths, but that video it was hard to actually see the actual cm or inches on the tape measure. The time was accurate because I stopped the frames and the timer showed the exact time in relevance to the position of the objects.
