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):
With roughly a 5% error due to distractions (TV, Children, and Dogs.).
#$&*
• What is the shortest time interval you think you would be able to measure with reasonable accuracy?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
a 3.0 seconds seems quite reasonable. More would get easier while less would get harder.
#$&*
• 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):
Due to a little error in a short time period would multiply the percent error with a greater effect vs. a littler error in a long period. It would get much greater percent error.
#$&*
• 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):
Within .1 seconds due to pause and replay only though.
