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 think I can measure the time between two events using the TIMER program pretty accurately. Even though the TIMER program can be unreliable sometimes, it can still give fairly accurate measurements.

• 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 accuracy can be measured up to 0.001 second difference between the two times. I gathered this number based on some of the experience I have had with using the TIMER programs. All of the times I have gotten from the TIMER program have had at most a 0.001 seconds difference.

• 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):
As the time between the events gets smaller, the percent error gets smaller and smaller as well. If the time events are small, then that means that the actual time will be closer to those times. If the time events are large than you won’t know where that actual time will lie. You won’t know if it’s closer to one number or the other because there is too big of a difference.

• 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):
I think that I measured the position of the ball and the pendulum in the initial video fairly accurately. However, I think that I could have done more to ensure better accuracy. For the positions of the ball I could have placed a mark on the incline I was using so that I could make sure that I started the ball at the exact location each time. For the pendulum I could have drawn a line to mark where the starting point is.
