The problem:

Answer the following:

• How accurately do you think you can measure the time between two events using the TIMER program?

I think I could accurately measure the time between 2 events within .5 seconds.

answer/question/discussion:

• What is the shortest time interval you think you would be able to measure with reasonable accuracy?

The shortest time interval measured would probably be around .3 seconds.

answer/question/discussion:

• How does the percent error in timing intervals change as the time between the events gets smaller?

The error percent would increase because it would be harder to measure.

answer/question/discussion:

• How accurately are you able to measure the positions of the ball and the pendulum in the initial video?

Within .5 seconds.

answer/question/discussion:

If you can only measure position accurately to within .5 seconds, how would it be possible to measure and interval lasting only .3 seconds?
