The problem:
Answer the following:
• How accurately do you think you can measure the time between two events using the TIMER program?
Based on the labs and my best judgment I would 0.01 sec when is fairly accurate.
• What is the shortest time interval you think you would be able to measure with reasonable accuracy?
I would have to say thousandths of a second possibly smaller, just ask Michael Phelps; he won an event by 0.001 seconds thanks to touch pads.
• How does the percent error in timing intervals change as the time between the events gets smaller?
As the time between intervals gets smaller that doesn’t mean the percent error get small in fact depending on the accuracy of your equipment your percent error might increase.
• How accurately are you able to measure the positions of the ball and the pendulum in the initial video?
Since I took the measurements at the beginning, middle and, end I believe that I was accurate to with ˝ inch or so because it was hard to pause the video at the right time.
