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 that I can accurately measure that time between two events, such as a start and stop. You can see when the object begins to move and when it finishes moving.

• 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 that the short the interval the more difficult it would be to measure. With shorter intervals, you would have to make sure that your start and stop techniques were very efficient.

• 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): I think that the percent error is greater with smaller time periods as opposed to larger time periods.

• 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 found it very hard to measure this experiment. I am not sure if it was because I was watching it as a video on the internet that made it more difficult. I felt that I either pressed the timer too early or too late.
