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: ->->->->->->->->->->->-> :
I think the timer program can be measured to the nearest one hundredth of a second. This is because in previous experience, there was no varying of number combinations between the hundredth decimal point.
• What is the shortest time interval you think you would be able to measure with reasonable accuracy?
answer/question/discussion: ->->->->->->->->->->->-> :
The shortest accurate time interval that could probably be measured is 0.01 second. However, a person may not be physically able to click the button in that brief amount of time.
• How does the percent error in timing intervals change as the time between the events gets smaller?
answer/question/discussion: ->->->->->->->->->->->-> :
The percent error increases as the time gets smaller because there is more human triggering uncertainty as well as uncertainty with the timer program.
• How accurately are you able to measure the positions of the ball and the pendulum in the initial video?
answer/question/discussion: ->->->->->->->->->->->-> :
In the initial video, the positions can be measured accurately the one inch. The cm marks are too blurred to read.
