he 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): It's hard to tell. Even if the timer hardware itself is accurate... It takes time for the eye to see the event, for the brain to process the information, for a signal to be sent out to the arm, for the arm to press the button and etc. I think the most accurate measurement is for to videotape everything and analyze the video frame by frame. Such would be difficult considering I'm doing the lab by myself.

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 would roughly say 0.1 second

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 will say the longer the event, the less inaccuracy. The shorter the event, the more inaccuracy.

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):
Probably within 0.1 of a second
