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 don't yet feel confident with my clicking. I don't feel like the mouse or pad on the
computer are responsive enough and I also don't trust my reaction time.

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 tried this out on the stop watch. I clicked start then stop. It took .33 seconds.

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 that when the time between events is longer, your brain has time to reset and
get ready for the next click. When the time between events gets smaller, I get nervous
about quick clicks.

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 had a lot of trouble with that. When I just watched it, it went so fast that I wasn't
sure of the order of events. However, even when I advanced it slowly, I had a lot of
trouble figuring out what was happening when. The movements of the ball and pendulum
were blurry. When I listened to it, I did somewhat better, but was still not feeling
certain about what was happening and when it was happening.
