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):
The TIMER program I would say is accurate when measuring the time between two events because it uses multiple decimal places, which means the more decimals that are the same, the more accurate the reading is.

• 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):
the shortest time interval that I think I could measure with reasonable accuracy would be reaction time. You can do many ways, one way I can think of it clicking the interval time at every 10 seconds and seeing how close you get to the actual 10s mark. This is measuring the accuracy of reaction time.

• 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 shorter the interval, the greater the uncertainty is as a percent of the timing. So as the interval gets bigger, the less the uncertainty or percent error. The more significant numbers, the less the percent error.

• 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):
In the initial video, in order to measure the ball and the pendulum, it was very difficult because you cannot be certain to the exact value. You are going by your eye sight to estimate where the ball or pendulum position is. One observer may measure the ball or pendulum from the beginning of the object, another may measure from the back of the objects, then another may measure from the middle of the objects. All three of these measurements have uncertainty because you are going by human error. Unless we had specific equipment that can tell us the exact time and position of where each the pendulum and a ball are, then our uncertainty is very inaccurate. I viewed them as to the closest inch, as it was top hard to determine within +/-1/8 of an inch. The clock had 4 decimal points, which would show more certainty, but without knowing the exact location at a specific time, the percent error increases.
