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:
Answer: I think you can very accurately measure the time between two events using the TIMER program because it times events to 6th decimal place. The only problem with accuracy when dealing with the TIMER program is human error.
• What is the shortest time interval you think you would be able to measure with reasonable accuracy?
answer/question/discussion:
Answer: I bet you have reasonable accuracy when dealing with times more than 2 seconds. From my previous experiments, I dealt with times around 2 seconds and each time trial was very close so we know it was fairly accurate.
• How does the percent error in timing intervals change as the time between the events gets smaller?
answer/question/discussion:
Answer: As the events are longer, the percent error decreases because the errors are the same as the shorter runs but the time is greater so the overall percent is small.
• How accurately are you able to measure the positions of the ball and the pendulum in the initial video?
answer/question/discussion:
Answer: My measurements were in a range of .2 seconds.
