Copy the problem below into a text editor or word processor.
• This form accepts only text so a text editor such as Notepad is fine.
• You might prefer for your own reasons to use a word processor (for example the formatting features might help you organize your answer and explanations), but note that formatting will be lost when you submit your work through the form.
• If you use a word processor avoid using special characters or symbols, which would require more of your time to create and will not be represented correctly by the form.
• As you will see within the first few assignments, there is an easily-learned keyboard-based shorthand that doesn't look quite as pretty as word-processor symbols, but which gets the job done much more efficiently.
You should enter your answers using the text editor or word processor. You will then copy-and-paste it into the box below, and submit.

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 you can accurately measure the time between two events using the TIMER program up to .01. I believe that is as accurate as it can get because anything much smaller than that didn’t look like it was accurate when we were doing that assignment using the TIMER.

• 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 the shortest time interval you could measure with reasonable accuracy would be a second because when we were using the TIMER program, the timer wasn’t very accurate when we were measuring fractions of a second. We were getting a lot of the same fraction of a second. However, when we were only pushing the button every few seconds it was much more accurate.

• 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):
I think the percent error in the timing intervals increases as the time between the events gets smaller. I think this because when we were doing the experiment with the TIMER program, the error was higher when the events happened at a fraction of a second as we could tell by the same fraction of a second appearing frequently. However when the event was happening every few seconds it was much more accurate so the percent error would be smaller here than when we are timing events that are closer together.

• 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 accurately measure the position of the ball down to the inch. I couldn’t really measure any smaller than that because the video wasn’t very clear and when it was paused it looked a little blurry. However, I was able to accurately see the bigger inch marks.
