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):
You could measure the time between two events fairly accurately. You would need to make sure that you hit the start and stop button and the exact moment in order to get a more accurate reading.
#$&*
• What is the shortest time interval you think you would be able to measure with reasonable accuracy?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
You could accurately measure a time period to the hundredth of a second with the timer program.
#$&*
• 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 error would become greater. The program cannot measure accurately very short periods of time.
#$&*
• 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):
You would be able to measure the time to the hundredth of a second.
