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):
I think that the TIMER program definitely causes some discrepancies. I believe it is accurate up to the hundredths place but no further. You must think about how the timer program rounds causing discrepancy.

• 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):
Probably about 0.05 seconds. I chose this because the program seems to round and doesn’t display every possible time interval. I think it rounds intervals under 0.05 seconds so 0.05 second intervals can be determined pretty accurately.

• 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 believe that the percent error probably increases because as the time within the events gets smaller you have to become more exact with your times causing you to go into more detail using more numbers giving you more room to cause 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):
Not very accurately, especially due to the quality of the video. I think I can accurately measure the position of the pendulum within 1 inch and the ball within half of an inch.
