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):
A certain amount of accuracy will be lost due to eye hand coordination and the eye/brains perception of where the object start/stops.
#$&*
• What is the shortest time interval you think you would be able to measure with reasonable accuracy?
answer/question/discussion (start in the next line):
.000125
#$&*
• 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):
I believe it would go up due to the lesser amount of time there is to react in between events.
#$&*
• 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):
The accuracy is not very high due to the blur caused by the quality of the camera and the fact that the objects are not next to each other in the sequence. This is compounded by the fact the measuring device is farther away still.
