How accurately do you think you can measure the time between two events using the TIMER program?

answer/question/discussion: ->->->->->->->->->->->-> The timer program gave non-repeating numbers in its results all the way to the thousandths decimal position. After that, I saw repeating sets of numbers showing the interval was to small to measure.

What is the shortest time interval you think you would be able to measure with reasonable accuracy?

answer/question/discussion: ->->->->->->->->->->->-> .141, because this was the smallest number I could get that did NOT have repetition after the thousandths place.

How does the percent error in timing intervals change as the time between the events gets smaller?

answer/question/discussion: ->->->->->->->->->->->-> The percent error would increase as the time interval became smaller since the speed of the computations would probably be to fast for the program to measure accurately.

How accurately are you able to measure the positions of the ball and the pendulum in the initial video?

answer/question/discussion: ->->->->->->->->->->->-> The accuracy varied slightly based on when I paused, but for the most part I was able to be accurate to the hundredths place all the time and the thousandths place if I paused without overlapping numbers.
