• How accurately do you think you can measure the time between two events using the TIMER program?
answer/question/discussion: ->->->->->->->->->->->-> :
I do not think the Timer program is completely accurate in the times that it gives. The numbers that it does give me though I think I can accurately measure the time between two events.
• What is the shortest time interval you think you would be able to measure with reasonable accuracy?
answer/question/discussion: ->->->->->->->->->->->-> :
I think the shortest time interval I would be able to measure with reasonable accuracy would be around 9 to 10 seconds, because while using the Timer program I found the beginning of these times had more accurate time intervals.
• How does the percent error in timing intervals change as the time between the events gets smaller?
answer/question/discussion: ->->->->->->->->->->->-> :
The percent error goes up when the time between events get smaller, because when the times get closer the more percent error there is.
• How accurately are you able to measure the positions of the ball and the pendulum in the initial video?
answer/question/discussion: ->->->->->->->->->->->-> :
I think I was pretty accurate in measuring the position of the ball and the pendulum in the video, but I could have possibly made errors because the video was not completely clear to see.
