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):
thousandth place, .001
#$&*
What is the shortest time interval you think you would be able to measure with reasonable accuracy?
answer/question/discussion: ->->->->->->->->->->->-> : ->->->->->->->->->->->-> (start in the next line):
.015
#$&*
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 actually increases(not decreases)when the events get smaller.
In larger numbers the difference between two events 2.54489 and 4.65422 you don't need to be as accurate because the answer is 2.10933. A much larger number can be off by 0.001 and not really affect it, but in smaller numbers the difference between 0.001 and 0.002 can be a huge difference
&&&&
percent error decreases

You haven't given a reason for this conclusion. The conclusion itself may or may not be correct; the reasoning will demonstrate which.

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):
position - 1/2, because the pendelum is think and the measuring tape is further away. when the video is paused the inch marks are still defined, but the more precise marks on the tape measure are hard to make out. To be sure I estimated it's position correctly, I would have a 1/2 error either way.
clock times .001 secs, because even when the video is stopped, the clock is still well-defined, unless the stick used to prop up the pendelum and tape at the beginning of the video gets in the way of the viewer and the clock time. At the three instances I stopped the clock time, I was able to make out the time to the nearest .001.
