The problem:

Answer the following:

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

between human error, timer accuracy/precision, and other elements, probably +/- .1

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

+/- .1

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

increases due to friction in the mouse button, and a persons ability to reset themself.

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

+/- .5
