The problem:
Answer the following:
How accurately do you think you can measure the time between two events using the TIMER program?
I think that the accuracy of the measurement in the TIMER program would be fair because there are series of trials that could be done and either support or disagree with our estimation.
What is the shortest time interval you think you would be able to measure with reasonable accuracy?
I think the shortest interval would be something that could be measured in a .00001 accuracy.
How does the percent error in timing intervals change as the time between the events gets smaller?
The intervals would leave a larger gap in the two different datas so hence we would need to show why and how there is the difference and how the percentage would support the timings though the events are smaller.
How accurately are you able to measure the positions of the ball and the pendulum in the initial video?
I dont think that I was accurate but my observations were estimation that I reliable because of the computer screen that recorded time.

It took me about 10 to 15 minutes to do this.

As you have seen from the first Timer exercise, the Timer program can make distinctions between several time intervals which lie between .1 sec and .2 sec, which is the range within which most quick click take place (a few students manage time intervals somewhat less than .1 second, and some report time intervals in excess of .2 sec). So the accuracy of the program in timing events triggered by mouse clicks is almost certainly better than .1 second.
The accuracy of an actual timing depends in addition on the consistency of the user's reaction time. Reaction time might or might not be consistent to within . 1 second.
