Answer the following:
How accurately do you think you can measure the time between two events using the TIMER program?
answer/question/discussion:
I think that I can accurately measure time between two events with high accuracy if the events are not closer than a hundredth of a second.
What is the shortest time interval you think you would be able to measure with reasonable accuracy?
answer/question/discussion:
Since the timer can differentiate between two points in time that are 0.0078125 seconds apart I should be able to measure accurately down to the hundredth of a second with high certainty, and to the thousandth with some certainty.
How does the percent error in timing intervals change as the time between the events gets smaller?
answer/question/discussion:
The percent error in timing intervals is not significantly affected in the tenths, only marginally affected in the hundredths, but in the thousandths or smaller the percent error becomes very large.
How accurately are you able to measure the positions of the ball and the pendulum in the initial video?
answer/question/discussion:
Since my computer can accurately measure up to 1/128 parts of a second I was able to measure accurately up to a hundredth of a second, which was sufficient to determine any difference between trials.
I'm not sure your measurements were accurate to within a hundredth of a second, though you computer might be able to achieve this accuracy.
I actually believe the timer program can distinguish intervals only down to 1/64 second, though it is possible that on some computers it could do better.
