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: ->->->->->->->->->->->-> :
Using the TIMER program, I think I could measure the time between two events to within 0.2 – 0.3 seconds, or possibly shorter. With a little more practice, I think I could reduce that number even more as I become more comfortable with using the program.
• What is the shortest time interval you think you would be able to measure with reasonable accuracy?
answer/question/discussion: ->->->->->->->->->->->-> :
A time interval of about 2 seconds is probably the shortest time interval I would be able to measure an event to within reasonable accuracy. Anything time interval shorter than that would not be very accurate.
• How does the percent error in timing intervals change as the time between the events gets smaller?
answer/question/discussion: ->->->->->->->->->->->-> :
The percent error would grow larger as the time between events gets smaller. The shorter the time interval between events, the harder it is to get an accurate measurement, the greater the chance of error, thus the larger percent error.
• How accurately are you able to measure the positions of the ball and the pendulum in the initial video?
answer/question/discussion: ->->->->->->->->->->->-> :
I believe I was able to measure the positions of the ball and pendulum with reasonable accuracy. The quality of the video was a little tough to make an overly accurate judgment, but I feel as though I did a pretty good job with the given circumstances.
