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 would say I could measure within .5 seconds of the actual time.
@&
I think you could improve on that. I expect you would be good to within .2 seconds, and probably within .1.

• 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):
1 second

• 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 in timing intervals gets higher as the events get 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):
I am not 100% accurate due to the fact that I am human and the video doesn’t have the best quality, but I would say I am at least 75 percent accurate.
