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):
Within 0.5 seconds fairly accurately and within 1 second very accurately.
#$&*
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):
Tenths of a second. I understand why people may say they could measure smaller units more accurately but hundreths of a second are just too small to measure with any certainty.

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 gets larger.
#$&*
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):
Accurately because those are uniform motions that I can get used to and time easily.
