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:
I believe that it will be fairly accurate but due to human interaction, there will be slight inaccuracy.
• What is the shortest time interval you think you would be able to measure with reasonable accuracy?
->->->->->->->->->->->-> answer/question/discussion:
I believe that the shortest time interval that I could record with reasonable accuracy would be around .5 second.
• How does the percent error in timing intervals change as the time between the events gets smaller?
->->->->->->->->->->->-> answer/question/discussion:
The percent error would increase with shorter time periods between events. This is due to the slow reflex of finger triggering and the eye to hand relay.
• How accurately are you able to measure the positions of the ball and the pendulum in the initial video?
->->->->->->->->->->->-> answer/question/discussion:
Not very accurately. This is due to the distance in the video and the speed that it moves. It takes many viewings to get a grasp of the relationship between the pendulum and the ball.
