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 don’t think the measure can be that accurate using the TIMER program. This is because the time that the TIMER gives you depends on when the person clicks the button, and they can’t really click on the precise time that the happening occurs.

• 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):
I think the shortest time interval I could measure with reasonable accuracy would probably be 0.1. That’s just according to the testing I did on the TIMER program.

• 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):
The program can’t round to the significant figures as well as the time gets smaller so it rounds to the same number, giving us a percentage error for our intervals.

• 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):
The measurements were as accurate as possible, but obviously not right on point. Different things factor in to timing these things such as when the pendulum or the ball is released related to when the timer is clicked. Also, it’s hard to determine when they reach final position, much less stop the clock at the exact time that it does. So, the measurements were definitely not as accurate as they could be, but they were as accurate as possible under the circumstances.
