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 it is accurate within a hundredth of a second, which is a small enough number that I think the program is reliable.

• 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 smallest interval at which it is accurate is a hundredth of a second (0.01)

I don't think you would be able to detect the beginning and end of an interval of length .01 second, so even though the TIMER is accurate to about that degree of precision, you wouldn't actually be able to time an interval that short.
Most people can't perform two clicks in much less than .2 seconds, but even with an interval of that length would be very difficult to trigger the TIMER accurately.

• 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 percent error gets larger as the time between events gets smaller.

• 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): It is possible to measure it fairly accurately, but not as accurately as if it were in person.
