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 think I can measure it fairly accurtily, the biggest reason my calculation would be off is me being able to start and stop the timer perfectly each time.

• 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 I would be able to measure within 0.1 seconds pretty accurately.

• 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 rises as the time gets smaller, because if you have a smaller number, it takes a small number to through it off even more. For example if the weight off a 250 pound man is 10 pounds off it doesn’t make too much of a difference, but if it is 10 pounds off a 80 girl, it makes a much larger difference.

• 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):

I think I was able to do that within of a quarter of inch because the video images were very blurry, as for the timer it did not have as many digits then the TIMER program so I suppose it is not as accurate.
