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):
the timer program can measure time between two events fairly accurate. it could be off, but not by very much at all.

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):
.01
this would be the most accurate because this is the fastest it can probably pick up to still be accurate.
@&
Good answer but note that whle the program could pick that up, very few if any human operators could time to that degree of accuracy.

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 will probably increase as the events gets smaller because you can only click the mouse so fast.

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):
you can puse the video to see how far along the tape is ( or where the pendulum is) and get it fairly accurate if you use the timer shown on the screen. however, if you tried to use the timer program, it wouldn't be as accurate.
&#This looks good. See my notes. Let me know if you have any questions. &#
