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 greater the time between two events the easier and more accurate the timer program is. With a longer time trial I estimate an accuracy around . 01
What is the shortest time interval you think you would be able to measure with reasonable accuracy?
answer/question/discussion: **************** something close to .5 second. It is hard to click that fast and try to catch the beginning and end of an event less than .5 second.
How does the percent error in timing intervals change as the time between the events gets smaller?
answer/question/discussion: **************** Remembering back to the first timer experiment it seems the faster the event the harder it is to get accurate readings therefore the percent error increases.
How accurately are you able to measure the positions of the ball and the pendulum in the initial video?
answer/question/discussion: **************** The pendulum did not travel as fast as the ball so it was easier to measure the position maybe to a .4-.5 of an inch and .1 seconds whereas the ball traveled faster and was located behind the pendulum. I only measured the pendulum but I would guess about the same accuracy maybe slightly less accurate .5-.7 of an inch and .1 - .5 seconds.
